Abstract
A phenomenological tensorial pattern has been proposed to
describe several thermomechanical behaviours of various materials [1-3]. The
study presented here aims at checking whether the theory is effective in
modelling the thermomechanical features of the cyclic viscoelastoplastic
behaviour of metallic materials at high rates of strain. Several types of
numerical illustrations of the cyclic behaviour including relaxation and creep
are proposed ; in order to suggest qualitatively that with the unique proposed
pattern, it is possible to take into account a cyclic behaviour at low strain
rate as well as at high strain rate.
