Abstract

Examples described herein relate to apparatuses and methods for predicting strength of a coupon of composite material. A first critical damage event and strain and stress distributions of the coupon is determined by performing a finite element analysis (FEA) of a finite element model of the coupon. The first critical damage event is associated with the strain and stress distributions. The strain and stress distributions are received as inputs to at least one surrogate model. A final load corresponding to a final failure of the coupon is determined using the at least one surrogate model.
