Continuum Mechanical Modeling of the Inelastic Response of Woven Textile Membranes

This work discusses the derivation and numerical implementation of an elastoplastic model textile membranes at finite strains. The mechanical accounts for anisotropic hyperelastic response [1], reached in saturation region. plastic anisotropy is modeled by implementing yield surface flow rule as a function structural tensor [2]. Furthermore, capability to simulate behavior under non-proportional cyclic loading investigated. For this purpose, fitting procedure identify elastic parameters presented.
