While several different specimen geometries are typically required to calibrate a ductile fracture locus model, this article presents for the first time a calibration methodology that uses one single specimen geometry. This is accomplished by a compu

This article focuses on predicting the instant of failure in a real scale component of complex geometry and loading using a ductile damage model calibrated exclusively on small-scale laboratory specimens of relatively simple shape. The ductile behavi

Ductile fracture locus models are extensively used in applied mechanics to predict the initiation of failure thanks to the ease of numerical implementation and simple calibration from experiments. Here, an attempt is made to investigate its potential

A continuum ductile damage and failure model coupled with metal plasticity is presented, with the focus on capturing different failure mechanisms and prediction of the strain localisation. The onset of diffuse necking and local thinning is observed i
