to ductile fracture associated with plastic deformation, without taking into account the …

Failure of metals I: Brittle and ductile fracture

A Pineau, AA Benzerga, T Pardoen - Acta Materialia, 2016 - Elsevier
This is the first of three overviews on failure of metals. Here, brittle and ductile failure under
monotonic loadings are addressed within the context of the local approach to fracture. In this …

Voids development in metals: Numerical modelling

W Wciślik, S Lipiec - Materials, 2023 - mdpi.com

structural metals through the nucleation, growth and coalescence of voids. In the present …

Ductile failure modeling

AA Benzerga, JB Leblond, A Needleman… - International Journal of …, 2016 - Springer
Ductile fracture of structural metals occurs mainly by the nucleation, growth and coalescence
of voids. Here an overview of continuum models for this type of failure is given. The most …
