“…This observation agreed with the proposals by Bai and Dodd [8], and by Rosenberg and Dekel [9] of the existence of adiabatic shear bands formed in the regions of the impact inside which temperatures higher than 720 • C may be reached, inducing the phase transformation.…”

“…Many advanced processes in engineering such as high-speed metal forming (Rojek et al, 2001), cutting (Miguélez et al, 2009;Molinari et al, 2010;Ma et al, 2012), crash in energy absorbing structures (Reyes et al, 2002;Rusinek et al, 2008) or impact on metallic plates (Rosenberg and Dekel, 2004;Rodríguez-Martínez et al (2010a,b)) involve large strains at high strain rates. In these conditions, the thermodynamic process deviates from the isothermal state and approaches adiabaticity, leading to large and sometimes very rapid variations in the temperature field.…”

a b s t r a c tWe present a thermodynamic scheme to capture the variability of the Taylor-Quinney coefficient in austenitic steels showing strain induced martensitic transformation at high strain rates. For that task, the constitutive description due to Zaera et al. (2012) has been extended to account for the heat sources involved in the temperature increase of the material. These are the latent heat released due to the exothermic character of the transformation and the heat dissipated due to austenite and martensite straining. Through a differential treatment of these dissipative terms, the Taylor-Quinney coefficient develops a direct connection with the martensitic transformation becoming stress, strain and strain rate dependent. The improved constitutive description sheds light on experimental results available in the literature reporting unusual ð> 1Þ values for the Taylor-Quinney coefficient.

The so-called viscoplastic consistency model, proposed by Wang, Sluys and de Borst, is extended here to the integration of a thermoviscoplastic constitutive equation for J 2 plasticity and adiabatic conditions. The consistency condition in this case includes not only strain rate but also the effect of temperature on the yield function. Using the backward Euler integration scheme to integrate the constitutive equations, an implicit algorithm is proposed, leading to generalized expressions of the classical return mapping algorithm for J 2 plasticity, both for the iterative calculation of the plastic multiplier increment and for the consistent tangent operator when strain rate and temperature are considered also as state variables of the hardening equation. The model was implemented in a commercial finite element code and its performance is demonstrated with the numerical simulation of four Taylor impact tests.
