A Triaxial Failure Diagram to predict the forming limit of 3D sheet metal parts subjected to multiaxial stresses [PDF]

, 2016
Accurate prediction of failure and forming limits is essential when modelling sheet metal forming processes. Since traditional Forming Limit Curves (FLCs) are not valid for materials subjected to triaxial loading, a new failure criterion is proposed in ...

Punch in a Punch: Validating FLC and fracture models for severe strain path changes [PDF]

MATEC Web of Conferences
While generating experimental linear loading strain paths is still required for the identification of Forming and Fracture Limit Curves, non-linear loading paths are necessary to validate models for industrial applications.

Applications of the Gurson’s model in sheet metal forming

MATEC Web of Conferences, 2018
Recent advances in the modelling of metals encompass modelling of metals structural inhomogeneity, damage, porosity, twinning/untwining and non-local and second order effects. This presentation is focused on modelling the void growth in ductile fractures.

The Maximum Flux of Star-Forming Galaxies [PDF]

, 2018
The importance of radiation pressure feedback in galaxy formation has been extensively debated over the last decade. The regime of greatest uncertainty is in the most actively star-forming galaxies, where large dust columns can potentially produce a dust-
