Abstract
For simplification purposes, damage in unidirectional carbon fiber-reinforced composites (CFRPs) under longitudinal tensile loading is neglected, hence maximum stress criterion is often used as the maximum bearing capacity. In this work, a progressive failure analysis focusing on predicting damage initiation and propagation associated to longitudinal loading (i.e. fiber direction) is proposed. A mathematical routine based on the classical laminate theory (CLT) and on failure criteria was developed to simulate the material behavior. This study will focus on unidirectional laminates under longitudinal tensile loading. Computational results are compared to experimental data available on the literature. The proposed approach is simple, conservative and able to offer good predictions, being ideal for a preliminary analysis.
