Abstract
A constitutive relation is formulated for coated fabrics that exhibit both elastic and inelastic, but time‐independent, responses. The nonlinear orthotropic response is represented by an elastic portion related to yarn stretch and coating shear, and an inelastic part related to crimp interchange. A method is proposed to compute the path‐dependent inelastic strain and the elastic strain for any loading once material parameters are evaluated from uniaxial tests in the principal directions of elasticity.Keywords
