Abstract

A micro method was presented to study tensile strength of stitched laminates.A geometrical model of local waviness of fiber around stitches was establisbed.Finite element methods were combined with bridging model and maximum stress criteria.Tensile strength of laminates was obtained based on the analysis of 0° ply.Good agreement is found between analytical and experimental results.
