In the paper, a new phenomenological interpretation of some of the principal temporal effects of high-rate plastic deformation of metals from a united viewpoint is represented. A …
In this paper a physical-based constitutive relation for defining the thermo-viscoplastic behaviour of FCC metals with dependence on strain on thermal activation processes is …

The lack of comprehensive insight and accurate description on the dynamic thermomechanical behaviors in high-temperature and high-strain-rate loading environment …
In this paper, a modified constitutive relation to model the dynamic strain aging phenomenon is proposed based on the previous model of Voyiadjis-Abed. The dynamic strain aging …
In this paper a study is presented on the experimental and numerical analysis of the failure process of mild steel sheets subjected to normal impact by hemispherical projectiles. The …
The lack of full stress-strain data sets under the coupled effect of high strain rates and elevated temperatures is one of the main concerns in a multi-hazard (blast and fire) …
In this paper are presented two extensions of the Rusinek–Klepaczko constitutive relation [Rusinek A, Klepaczko JR. Shear testing of sheet steel at wide range of strain rates and a …
