A ductile damage model, which fully couples classical void growth at high stress triaxiality
and Coulomb ductile model at the slip system scale at low stress triaxiality, was applied for …

Porous plasticity aims to model the growth and coalescence of voids leading to ductile
failure. The GTN model (1984), resulting from heuristic modifications to Gurson's …

A load path change (LPC) from shear to tension has been studied for a recrystallized 2198
T8 aluminium alloy sheet material by three-dimensional (3D) X-ray imaging combined with …

The thermal stability of the lightweight, T83 heat treated 2099 Al-Cu-Li alloy was assessed in
the temperature range 200–305° C, through both hardness and tensile tests after overaging …

Ductile fracture of metallic alloys in shear-dominated loadings is usually modeled either with
uncoupled failure criteria or with porous plasticity. In the first approach, criteria depending on …

Damage and strain changes during shear dominated loading were assessed in situ via
synchrotron laminography. In combination with digital volume correlation (DVC), local strain …

The aim of this investigation is to evaluate the microstructural features, material flow, and
postweld mechanical properties of a dissimilar joint made of AA2024-T3 and AA2198-T3 …

The deformation and damage micromechanisms ahead of a notch in a large flat specimen
have been assessed using in situ synchrotron laminography combined with digital volume …

An attempt is made here to capture numerically slant ductile fracture and its early slant strain
precursors via combining a dynamic strain aging (DSA) model with ductile damage models …

The influence of different filler materials on the microstructure, tensile mechanical properties,
and fracture toughness of laser beam welded AA2198 alloy as well as the effect of different …
