Abstract

Systems and methods for semi-discrete modeling of progressive damage and failure in composite laminate materials are disclosed. An example method includes receiving, from a user, a fibrous strip width and a fibrous strip spacing, and creating a finite-element (FE) mesh by: generating, using a structured hex meshing algorithm, a plurality of fibrous strips along a fiber direction based on the fibrous strip width and the fibrous strip spacing, and generating, using a free hex-dominated advancing front meshing algorithm, a bulk element between each of the plurality of fibrous strips. The FE mesh may define a portion of a composite laminate material. The example method 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 stress value or a strain value to the constitutive model to generate the predicted mechanical response.
