Determination of material parameters for Abaqus progressive damage analysis of E-glass epoxy laminates

A methodology for determination of material parameters for the progressive damage analysis (PDA) model implemented in Abaqus is presented. The methodology is based on fitting PDA model results to available experimental data. The applicability of the PDA model is studied by comparison to a broad set of experimental data for E-glass epoxy laminates, as well as contrasting PDA with ply discount results. Also, sensitivity of the Abaqus PDA model to h- and p-refinement is studied.
