Numerical simulation of void elimination in the billet during hot shape rolling processes based on the Gurson–Tvergaard–Needleman model

AIP Advances
The presence of voids can compromise the strength and continuity of downstream products. The Gurson–Tvergaard–Needleman model was utilized to obtain the relevant parameters.

Thermomechanical Analysis of PBF-LB/M AlSi7Mg0.6 with Respect to Rate-Dependent Material Behaviour and Damage Effects

Applied Mechanics
This paper describes the self-heating effects resulting from mechanical deformation in the additively manufactured aluminium alloy AlSi7Mg0.6. The material’s self-heating effect results from irreversible changes in the material’s microstructure that are ...

A local stress approach for ductile crack propagation (Integration into the GTN model framework and demonstrations)

Mechanical Engineering Journal
A local stress approach, employing failure conditions derived from notched round-bar tensile tests has successfully traced the ductile crack propagation in compact tension (CT) specimens. The failure condition is expressed using the failure stress index (
