摘要: The paper deals with an evaluation of the multi-mechanism (MM) approach capabilities in prediction cyclic behavior different classes metallic materials. For this objective, tests detailed (Taleb, Int J Plast 43:1–19, 2013a) have been simulated here by MM model. In these tests, six alloys were considered: two ferritic steels (35NCD16 and XC18), austenitic stainless (304L 316L), one “extruded” aluminum alloy (2017A) copper-zinc (CuZn27). specimens subjected to proportional non-proportional stress as well combination strain control at room temperature. identification material parameters has carried out using exclusively controlled experiments under loading paths performed present study for each material. model may describe a large number phenomena twenty five total but, it appears that given adopted conditions, activation all be not necessary. Our attention was focused mainly on predict correctly accumulation inelastic including shape hysteresis loops. comparison between test responses their predictions are generally satisfactory relatively small (between eight thirteen according material). One can also highlight capability transient ratcheting without dynamic recovery term kinematic variables. Finally, deserves improvement better description anisotropic
