Guided by previous theoretical analyses, an experimental program was designed to probe
the path-dependence of the fracture locus in ductile materials. The material and loading …

Based on experiments and computational modeling, this study examines the failure
behavior of structural steel, HY-100, which has been pre-strained at a high stress triaxiality …

The present paper is concerned with the development of a general macroscopic fracture
criterion for a crack-free ductile material. For an isotropic plastic body the mechanical state is …

The effect of loading path on the fracture locus was examined theoretically by means of cell
model calculations. Two-dimensional axisymmetric finite element analyses were conducted …

It is widely accepted that damage due to plastic deformation and ductile fracture in metals
greatly depends on the triaxiality level (T) of the stress tensor, but according to recent …

Fracture of ductile materials has frequently been observed to result from the nucleation,
growth and coalescence of microscopic voids. Experimental and analytical studies have …

Basic ductile fracture experiments for sheet metal (or flat coupons extracted from bulk
material) are presented to characterize the onset of fracture at different stress states. Special …

Until recently, the engineering application of fracture mechanics has been specific to a
description of macroscopic fracture behavior in components and structural parts which …

An isotropic multi-surface model of porous material plasticity is derived and employed to
investigate the effects of the third stress invariant in ductile failure. The constitutive relation …

This paper treats the ductile failure initiation in circumferentially-notched tension specimens
and explores the local damage model that is able to represent the continuous degradation of …
