Computational Simulation of Progressive Fracture in Fiber Composites

Conference paper

Abstract

Computational methods for simulating progressive fracture in fiber composite structures are presented. These methods are integrated into a computer code of modular form. The modules include composite mechanics, finite element analysis, and fracture criteria. The code is used to computationally simulate progressive fracture in composite laminates with and without defects. The simulation tracks the fracture progression in terms of modes initiating fracture, damage growth and laminate imminent global (catastrophic) fracture.
