	recorded ground accelerations often show drifts much larger than
	those expected for the true ground displacements. These drifts might
	be due to many things, including dynamic elastic ground tilt, inelastic
	ground deformation, hysteresis in the instruments, and cross feed
	due to misalignment of nominally orthogonal sensors. This article
	shows that even if those effects were not present, the analog-to-digital
	conversion (ADC) process can produce apparent “pulses” and offsets
	in the acceleration baseline if the ground motion is slowly varying
	compared with the quantization level of the digitization. Such slowly
	varying signals can be produced by constant offsets that do not coincide
	with a quantization level and by near- and intermediate-field terms
	in the wave field radiated from earthquakes. Double integration of
	these apparent pulses and offsets leads to drifts in the displacements
	similar to those found in processing real recordings. These effects
	decrease in importance as the resolution of the ADC process increases.}

	standard solid model, that is, a three-element model. The analytical
	solutions are derived for a half-space of the viscoelastic material
	based on the method of functional equations. These solutions can
	apply to the response of compressible as well as incompressible coated
	layers to a spherical-tip indentation. The results include convenient
	closed-form formulas for approximating both relaxation testing and
	creep testing. They establish a fundamental basis for probing mechanical
	properties of polymeric coatings on substrates with nanoindentation
	or microindentation tests. Comparisons are made on the tests of both
	bulk polystyrene (PS) and drying semicrystalline polyvinyl alcohol
	(PVOH) coatings on a silicon wafer to verify the application of analytical
	solutions to viscoelastic polymers. The moduli obtained for bulk
	PS correspond with literature values well. While the results from
	PVOH coatings show good agreement between elastic unloading and viscoelastic
	models in 10% relative humidity, the viscoelastic model gives a considerably
	lower value after long-term holds in 70% relative humidity. This
	is partially attributed to a strain rate e.ect.

	methods are compared on the basis of data collected on 31 sensitive
	clay sites in Quebec whose preconsolidation pressure profiles are
	well known. Each method is briefly presented and the most promising
	are identified. The simplest method, which directly relates preconsolidation

	tool used to determine pore pressure and hydrologic properties within

	Program (ODP) on ODP Leg 204 in July 2002. Analysis of the piezoprobe
	data suggests that in situ pore pressure is 9.5 MPa, which is approximately
	the hydrostatic pressure (9.53 MPa). The piezoprobe deployment and
	modeling of the results provides one of the first measurements of
	in situ permeability made within the borehole. From the piezoprobe
	dissipation data, we estimate in situ permeability of approximately
	1.5 
 10-17 m2 for the hemipelagic clay. This is consistent with
	laboratory-measured permeability (~1x10–17 m2) on hemipelagic clay
	samples from nearby ODP Site 892. The piezoprobe results were compared
	to a Davis-Villinger Temperature/Pressure Probe (DVTP-P) measurement
	made at the same depth, and in the same lithology, but in an adjacent
	borehole. The DVTP- P is also a penetration-based tool, however it
	has a much wider probe diameter. The DVTP-P generated a higher peak
	pressure that did not dissipate as much as the piezoprobe pressure,
	which resulted in a DVTP-P estimate of in situ pressure that nearly
	equals the overburden stress. The results suggest that a narrow diameter
	probe like the piezoprobe can be used to rapidly determine in situ
	pressure and hydrologic properties in sites investigated by the Ocean
	Drilling Program.}

	can be measured to derive mechanical properties of the target material.
	Several such dynamic penetrometers will be used on Mars, the Moon,
	Titan, and a comet nucleus. However, solid bodies in the Solar System
	exhibit a wide range of surface atmospheric and gravitational conditions
	and previous workers have shown that changes in ambient pressure
	or gravity can significantly alter penetration dynamics. This presents
	a challenge for the terrestrial calibration of penetrometers. We
	have applied a penetration model to low speed impacts in air and
	vacuum, with the aim of quantifying any differences in a target's
	measured properties. A 1.05 kg instrumented penetrometer was dropped
	onto two cohesionless granular materials at speeds of around 2.7
	m s-1. The apparatus was located in a vacuum chamber, allowing tests
	to be made at low pressures. An initial upper limit for the mean
	deviatoric stress (a measure of material strength) was found in each
	case by dividing the gravitational potential energy lost (during
	the penetrometer's fall and penetration) by the volume penetrated.
	This value can be reduced using the projectile's recorded deceleration
	and a penetration model that includes friction and dynamic resistance.
	Good fits between the recorded and modelled deceleration were obtained
	for a range of values of dynamic drag coefficient and coefficient
	of friction. Initial comparison of the air and vacuum drops performed
	so far suggests behaviour consistent with that described by previous
	workers, namely that pore pressure aids penetration in loose materials
	but inhibits penetration in heavily compacted materials, and that
	these effects are larger for smaller grain sizes.},

  abstract = {he rheological behavior of some sensitive clays has shown that there
	are positive relationships between plastic viscosity, yield stress,
	remolded shear strength, and liquidity index. Based on the various
	correlations, remolded strength values can be predicted for soils
	with a liquidity index as high as 6. For a liquidity index varying
	from 2 to 5, the remolded undrained shear strength and plastic viscosity
	vary from about 90 to 5 Pa and from 200 to 7 mPa∙s respectively.
	It has been observed that most sensitive clays behave either as a
	Bingham or a Casson fluid, the latter behavior being related to less
	sensitive clays of higher pore-water salinities. Increasing the salt
	content from 0.5 to 30 g/L modified the rheological behavior of a
	single test soil from that of a Bingham to that of a Casson type
	of fluid. Such modification in the pore-water salinity illustrates
	how soils can have similar plastic viscosity and similar remolded
	strength but different yield stresses. The range of viscosity measured
	for sensitive clays is very different from that of values obtained
	from back analysis of subaerial or submarine slides where viscous
	flow can be expected.},

	and strains caused by shallow undrained penetration of piles and
	caissons in clay. The formulation combines previous analyses for
	steady, deep penetration,1 with methods used to compute soil deformations
	due to near-surface ground loss,2 and is referred to as the Shallow
	Strain Path Method (SSPM). Complete analytical solutions for the
	velocity and strain rates are given for a planar wall, an axisymmetric,
	closed-ended pile and unplugged, open-ended pile geometries. In these
	examples, the analyses consider a single source penetrating through
	the soil at a constant rate, generating a family of penetrometers
	with rounded tips, referred to as simple wall, pile and tube geometries.
	Soil deformations and strains are obtained by integrating the velocity
	and strain rates along the particle paths. The transition from shallow
	to deep penetration is analysed in detail. Shallow penetration causes
	heave at the ground surface, while settlements occur only in a thin
	veneer of material adjacent to the shaft and in a bulb-shaped region
	around the tip. The size of this region increases with the embedment
	depth. Deformations inside an open-ended pile/caisson are a§ected
	significantly by details of the simple tube wall geometry.}

	fall freely to penetrate the sea-bed soil. Successive integrations

	of velocity and displacement of the corer. These results, together

	of the soil to be calculated as a function of depth below the soil

	downward fluid flow is abnormal for a classical passive margin. We

	fluids by sediment compaction (on the continental rise), of a large-scale
	flow system stimulated by thermal buoyancy (100 km wide) related
	to the volcanic activity on the island of La Palma. q2000 Elsevier

  abstract = {This paper presents a new framework for elastic viscoplastic (EVP)
	constitutive modelling. In developing the model, a general one-dimensional
	elastic viscoplastic (1D EVP) relationship is first derived for isotropic
	stressing conditions using an "equivalent-time" concept. This 1D
	EVP model is then generalized into a three-dimensional EVP model
	based on Modified Cam-Clay and viscoplasticity. Fitting functions
	are proposed for fitting data when model parameters are being determined.
	Using these functions, a specific EVP model is developed which describes
	the time-dependent stress-strain behaviour of soils under triaxial
	stress states. This model has been calibrated using data from a densely
	compacted sand-bentonite mixture. The calibrated model is used to
	compute time-dependent (or strain rate dependent) stress-strain curves
	from a multistage shear creep test and a step-changed, constant strain
	rate undrained triaxial compression test. Predictions from the EVP
	model are in general agreement with measured values. It is demonstrated
	that the model can simulate accelerating creep when deviator stresses
	are close to the shear strength envelope in a q creep test. It can
	also model the behaviour in unloading-reloading and relaxation. Limitations
	and possible improvements are also indicated.},

  abstract = {The deformation and pore-water pressure responses of clayey soils
	are of great interest to civil engineers. In this paper, displacements
	and pore-water pressures of a clay subjected to the loading of a
	strip footing are simulated using a fully coupled finite-element
	(FE) consolidation method incorporated with a newly developed 3D
	elastic viscoplastic (EVP) model for the clay. A brief introduction
	to the 3D EVP model and its implementation in the FE analysis is
	presented. The 3D EVP model can describe the time-dependent stressstrain
	behavior of clayey soils, including volumetric creep. The main objective
	of this paper is to examine how the viscosity (or creep parameter
	c/V) of the clay affects the deformation and pore-water pressure
	responses of the clay. For this, the value of the creep parameter
	c/V is varied in the FE analysis. When viscous nature is taken into
	account, the pore-water pressure in the soil is higher than that
	without consideration of the viscous nature. The phenomenon of pore-water
	pressure increase due to creep is studied in this paper. It is found
	that larger creep parameter c/V results in higher pore-water pressure
	and larger deformation in the soil. The difference of the pore-water
	pressure due to the Mandel-Cryer effects and the creep is investigated
	using the FE model and discussed in this paper. In addition, a few
	other parameters (Poisson’s ratio n, permeability k, clay layer thickness
	h, and thickness h to a half footing width a ratio h/a) are also
	varied to investigate their influence on deformation and pore-water
	pressure of the soil with creep. It is found that, the lower the
	permeability of soil, the higher is the pore-water pressure and the
	larger is the local deformation. The thickness of the soil layer
	also has a great influence on the pore-water pressure induced by
	the viscous effect. All these increased pore-water pressures result
	from a balance of the pore-water pressures induced by creep (and
	the Mandel-Cryer effects or both) and dissipated because of drainage.}
