Material Characteristics of a Laminated Composite Shell

Application ID: 67691


This model serves the purpose of validation and verification of the Linear Elastic Material, Layered model in the Shell interface. In COMSOL Multiphysics, composites are analyzed either based on Layerwise 3D elasticity theory through the Layered Shell interface or based on FSDT-ESL theory through the Shell interface.

The First Order Shear Deformation Theory (FSDT-ESL) is implemented in the Linear Elastic Material, Layered model in the Shell interface available with the Composite Materials Module. This theory treats a heterogeneous laminated composite as a statically equivalent single layer. ESL theory reduces a 3D continuum problem to an equivalent 2D problem, reducing the problem size and computational time.

This example is a NAFEMS benchmark, described in Benchmarks for Membrane and Bending Analysis of Laminated Shells, Part 2: Stiffness Matrix and Thermal Characteristics. The effective flexibility matrices, effective stiffness matrices, effective thermal expansion coefficients, and midplane strains are compared with theoretical and numerical results given in the benchmark.
