Abstract

This study focuses on modelling of mechanical behaviour of threadlike woven materials or shaped in uniaxial form such as wires, ropes, woven lines, cables, straps, slings etc. The proposed one-dimensional model is based on the superimposition of two stress contributions: a non-Newtonian visco-elastic stress and a time-independent stress. The time-independent stress stands for a particular irreversible behaviour, linked to the loading history. This model neglects the thickness of the time independent hysteresis loops during the unloading-reloading processes while preserving the irreversible character of elastoplastic type behaviour. The model's predictions are compared to a set of experimental results, carried out on polyamide 6-6 (PA66) straps. The model describes the shape of the stress-strain hysteresis loops very well and predicts perfectly the direction of the strain or stress evolution during the creep or relaxation periods, regardless of their position in the first load or in the load-unload branches.
