 <p>This study case aims to verify the Rayleigh-Ritz implementation made with Composipy (Silva, R.P. 2023). Mathematical verification of the Rayleigh-Ritz implementation is made against analytical buckling equation and FEM model. The benchmarking example is a simply supported plate with biaxial load, which considers a quasi-isotropic layup [(45/-45)2/02/902]s and properties according Table below. This example came from Kassapoglou (2010).</p>

 <p>Dimension of the square plate is 100 mm and the load ratio (𝑁𝑦/𝑁𝑥) is 0.5. Analytical solution for this problem using Equation below is 234.7 N/mm.</p>
