摘要

A simplified micromechanics approach is used to develop a mathematical model to predict damage growth in prestressed plain weave fabrics near sites where yarns are broken. Stress concentration in the yarns neighboring yarn breaks is determined as a function of increasing loading. An evaluation of the load redistribution around the damage region includes a determination of the frictional slip of broken yarns, Consid- eration of equilibrium and deformation of constituent yarns leads to linear differential equations for yarn displacements applicable to distinct regions where slipping does and does not occur.
