This paper reviews the most recent models for description of the anisotropic plastic behavior
and formability of sheet metals. After a brief review of classic isotropic yield functions, recent …

This work outlines a rigorous variational-based framework for the phase field modeling of
ductile fracture in elastic–plastic solids undergoing large strains. The phase field approach …

In this study, the ER321 stainless steel is fabricated by wire and arc additive manufacturing
(WAAM) assisted with ultrasonic impact treatment (UIT). The mechanical properties and …

In this study, the ductile fracture of the alloy metal is analyzed. First, the key factors affecting
the initiation of ductile fracture are investigated. Then, a new uncoupled ductile fracture …

A ductile fracture criterion is newly proposed to model fracture behavior of sheet metals for
nucleation, growth and shear coalescence of voids during plastic deformation. In the new …

A macroscopic ductile fracture criterion is proposed based on micro-mechanism analysis of
nucleation, growth and shear coalescence of voids from experimental observation of fracture …

A ductile fracture model is proposed to describe shear fracture of sheet metals from shear to
balanced biaxial tension via uniaxial and plane strain tension. The fracture criterion models …

During deformation of aluminum (Al) alloys, there are three kinds of voids being formed by
distinct mechanisms, ie, matrix-cracking voids (MCVs), particle-cracking voids (PCVs), and …

One of the most confounding controversies in the ductile fracture community is the large
discrepancy between predicted and experimentally observed strain-to-failure values during …

A reliable prediction of structural failure is extremely important in industrial applications. The
promising phase-field model has been intensively studied in fracture simulation and been …
