Publisher Summary An important failure mechanism in ductile metals and their alloys is by
growth and coalescence of microscopic voids. In structural materials, the voids nucleate at …

The past 20 years have seen substantial work on the modeling of ductile damage and
fracture. Several factors explain this interest.(i) There is a growing demand to provide tools …

Many solids, including geomaterials and commercially available metallic alloys, can be
considered as a porous media. The Gurson-like model has been proposed to describe …

A damage plasticity model for ductile fracture is proposed. This model is established on the
cylindrical coordinate system of principal stress space. Experimental results show that …

Various fracture criteria, based on different assumptions and different mechanical models,
have been proposed in the past to predict ductile fracture. The objective of this study is to …

Deformation and fracture are investigated at room temperature in steel through tension and
compression tests. Round smooth bars and cylinders are used to characterize the …

This contribution provides an improvement on GTN model upon the prediction of fracture
location within low level of stress triaxiality. In the proposition, two distinct damage …

Ductile fracture is often considered as the consequences of the accumulation of plastic
damage. This paper is concerned with the application of a recently developed damage …

The modeling of failure in ductile materials must account for complex phenomena at the
micro-scale, such as nucleation, growth and coalescence of micro-voids, as well as the final …

This paper aims to predict ductile fracture of mild steel under monotonic loading only from
the test results of notchless tensile coupons. A simple fracture model based on the concept …
