An Stress Correction Method Applied to Doubly Curved Composite Laminated Plate

Article Preview

Abstract:

Aim: presents a stress correction method to improve calculation accuracy of doubly curved composite laminated plate with big meshing size to save computational effort. With the application of Marc’s secondary development function, a subroutine is embedded to simulate the mechanical properties of material, and the amendment factors are added so that the stress calculation results have the same computational accuracy when the model is compartmentalized to big meshes as the case under small meshes. We Compare the calculation results in big meshes and what in small meshes, which prove the error request can be satisfied.
