Abstract

This paper addresses the issue of stress re-distribution in the presence of a fiber fracture in a composite lamina. The state of stress after fiber fracture is influenced by several factors including matrix plasticity and interfacial debonding. Stress elevation in the fiber adjacent to the broken fiber is the focus of this study. The stress concentration effects in the vicinity of the fiber break and its influence on the neighboring intact fiber is analyzed using finite element method. The local stress field undergoes a substantial change if the fiber break is followed by interfacial debonding. Matrix yielding and the propagation of plastic front are other contributing factors to the local stress distribution. The specific case of SCS-6/Ti-15-3 where matrix plasticity has been observed experimentally is considered as the model MMC system in this work.
