| Abstract: | A stress amendment methodology is presented to improve the computational accuracy of doubly curved laminate composite under big meshes.With the application of Marc secondary development,a subroutine is embedded to simulate the mechanical properties of material,and the amendment factors are added so that when the model is compartmentalized to big meshes the stress calculation results have the same computational accuracy as the case under small meshes. |

| Keywords: | doubly curved laminate composites big meshes high accuracy |
