Regularizational approach for modeling ductile damage [PDF]
MATEC Web of Conferences, 2019 It is well known, that modeling of material softening behavior can lead to ill-posed boundary value problems. This, in turn, leads to meshdependent results as far as the finite-element-method is concerned [1].

Experimental techniques for ductile damage characterisation [PDF]
Procedia Structural Integrity, 2016 Ductile damage in metallic materials is caused by the nucleation, growth and coalesce of voids and micro-cracks in the metal matrix when it is subjected to plastic strain. A considerable number of models have been proposed to represent ductile failure focusing on the ultimate failure conditions; however, only some of them study in detail the whole ...

Low cycle fatigue of components manufactured by rod extrusion: Experiments and modeling
Advances in Industrial and Manufacturing Engineering, 2023 The performance of formed components is significantly influenced by the initiation of ductile damage. Preceding forming operations, for instance, affect the service life determined in fatigue tests.

Correlating Ultrasonic Velocity in DC04 with Microstructure for Quantification of Ductile Damage
Journal of Manufacturing and Materials Processing, 2023 The detection of ductile damage by image-based methods is time-consuming and typically probes only small areas. It is therefore of great interest for various cold forming processes, such as sheet-bulk metal forming, to develop new methods that can be ...
