Bending of a Simply Supported Composite Laminate
Application ID: 67641
This example demonstrates the bending analysis of a simply supported composite laminate under sinusoidal distributed transverse load. The composite laminate is thick, with a thickness to side length ratio of 1/4. The laminate has three layers in a cross-ply layup. The model is solved using both the Layerwise (LW) theory and the Equivalent Single Layer (ESL) theory.
This is a verification example where the results computed from both theories are compared to the exact 3D elasticity results as given in the reference. The through-thickness variation of the in-plane normal stress, the transverse normal stress, and the transverse shear stresses in each layer is compared to the reference results.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
