Stress-Strain Response of Fabrics under Two-Dimensional Loading. Part I: Racetrack Yarn Cross-Section

Abstract

A theoretical analysis of the load-elongation behavior of idealized plain-weave fabrics comprised of yarns having a racetrack cross-section and subjected to biaxial stresses is presented. Fabric strains resulting from both crimp interchange and yarn extension are considered. The analytical expressions derived have been solved with a digital computer for both extensible and linearly elastic materials. Generalized plots of the results are presented for two extremes of initial fabric structure: (1) equal crimp distribution in both sets of yarns; (2) one set of yarns noncrimped -- straight.
