Experimental characterization and numerical modeling of micromechanical damage under different stress states [PDF]

, 2013
The use of HSLA steels for the manufacture of automotive components is interesting from an engineering point of view. This family of steels, while possessing high strength, also has good formability and can be used in forming manufacturing processes.

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 ...

Thermomechanics of solid materials with application to the Gurson-Tvergaard material model

, 1997
The elastic-plastic material model for porous material proposed by Gurson and Tvergaard is evaluated. First a general description is given of constitutive equations for solid materials by thermomechanics with internal variables.

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 (

A detailed description of the Gurson-Tvergaard-Needleman model within a mixed velocity-pressure finite element formulation

, 2013
International audienceIn an effort to implement Gurson-type models into a mixed velocity-pressure finite element formulation with the MINI-element P1+/P1, the algorithm proposed by Aravas (IJNME, 1987) to integrate the pressure dependent plasticity as ...
