Simplified micromechanical models for analysis of interface debonding in a fibrous composite

The objective of this study is to develop simplified micromechanical models to analyze the interface debonding between fiber and the matrix materials. Both analytical and simplified finite element models are used to predict the effective transverse elastic modules of fibrous composites with a partial interface crack based on the material properties of their constituents. The simplified finite element model uses springs in the connecting nodes between the fiber and matrix. A detailed finite element analysis, which is programmed using the MATLAB engineering software is performed to check the accuracy of the simplified models. The simplified models yield accurate effective transverse elastic modulii of various composites with partial interface cracks when compared to the results obtained from detailed finite element analyses.
