JEBAHI, Mohamed; ; ABED-MERAIM, Farid (Elsevier, 2020)
The present paper proposes a flexible Gurtin-type strain gradient crystal plasticity (SGCP) model based on generalized non-quadratic defect energy and uncoupled constitutive assumption for dissipative processes. A power-law ... -

In the present work, a rigorous and consistent thermo-viscoelastic-viscoplastic ductile damage model is proposed to address the variability of the Taylor-Quinney coefficient (the storage to anelastic energy rate ratio) ...

The effect of temperature on perforation behavior of 304 austenitic stainless steel plates was investigated experimentally. Perforation tests have been conducted at velocities from 80 to 180 m/s and temperatures between ...

Conférence invitée; ;BALAN, Tudor; ABED-MERAIM, Farid (2015)
The aim of this work is to develop a dislocation density based model for IF and DP steels that incorporates details of the microstructure evolution at the grain-size scale. The model takes into account (i) the contribution ...

A number of parts and components involved in the automotive industry are made of thin bent sheets, which are subjected to out-of-plane compressive stresses in addition to traditional in-plane stresses. Unfortunately, the ...
