Abstract

Systems and methods for semi-discrete modeling of delamination migration in composite laminate materials are disclosed. An example method includes receiving a specimen geometry and a specimen stacking sequence. The example method also includes creating a finite-element (FE) mesh that defines a composite laminate material by: generating, using a mesh generation tool, a plurality of plies shaped according to the specimen geometry, and connecting the plies together based on the stacking sequence by placing cohesive elements between each adjacent pair of plies. The example method also includes determining a predicted mechanical response of the composite laminate material by: generating a constitutive model corresponding to the composite laminate material based on the FE mesh, and inputting a strain value to the constitutive model to generate the predicted mechanical response.
