Viscoelastoplastic cyclic behaviour of sail materials
Résumé
A tensorial visco-elasto-hysteresis model has been used previously in order to describe the thermomechanical behaviour of woven fabrics. Thus, it takes into account the essential features of behaviour, such as the steady state viscous stress as a function of strain and strain rate, the time-independent irreversible behaviour and the instantaneous modulus increasing with the strain. The aim of the study is to suggest the interest of the theory in the field of sail fabrics concerning characterization, testing and design. Moreover, we focus attention on two questions which are of fundamental interest, both at the level of principles and in the field of technological research, namely the viscous behaviour of sail fabrics and his nonlinear character.
