The assumption of a constant friction force (simple slip assumption) on broken slipping
yarns, which has been used in the micromechanical analysis of damage growth in stressed
plain weave fabrics, is evaluated. In this analysis, the frictional traction on slipping yarns is
variable. It starts from zero at the cut end of the yarn and approaches a constant value with
exponential behavior, where the steepness of the approach depends on a parameter γ. The
stress concentration factor (SCF) is determined for various values of γ as a function of
increased loading. For values of γ that are expected to be physically realistic for most
fabrics, the obtained SCF differs from that using the simple slip assumption by about 5%.
