Abstract

The purpose of this study is to develop a model to predict residual strength of composite materials with barely visible impact damage (BVID) which is the key factor for the composite structures certification. The portion for the energy from impact is used to form microcrack system in matrix, fiber and interface media. The proposed algorithm calculates the worst distribution of damages and then estimates the residual strength of composite. Thus, the BVID allowables can be established using less experiments.
