Modeling of the cyclic visco-elasto-plastic one-dimensional behavior of polyamide-based woven straps

This study focuses on modeling the mechanical behavior of threadlike woven materials or those shaped in uniaxial form, such as wires, ropes, lines, cables, straps, slings, etc. The proposed one-dimensional model is based superimposition two stress contributions: a non-Newtonian visco-elastic and time-independent stress. represents particular irreversible behavior, linked to loading history. neglects thickness hysteresis loops during unloading–reloading processes while preserving character elasto-plastic-type behavior. model's predictions are compared set experimental results, carried out polyamide 6-6 available from previous studies literature. describes shape stress–strain very well predicts perfectly direction strain evolutions creep relaxation periods, regardless their position first load load–unload branches.
