Severe Plastic Deformation (SPD) leads to grain refinement and strengthening of metals. The most utilized SPD techniques are Equal Channel Angular Pressing (ECAP), High Pressure Torsion (HPT) and Multi-Axial Compression (MAC). Only MAC allows the det

Severe plastic deformation (SPD) of metals leads to their strengthening and grain refinement, but to low uniform elongations. Low Strain Amplitude Multi Directional Forging (LSA-MDF) is an important method for increasing this low uniform elongation.

A mathematical model of ductile fracture behavior is devised by considering fracture incipience as a void deformation limit phase. To this end, two major void deformation modes, viz., void dilation and void elongation/rotation are carefully considere

This paper is a contribution to the prediction of edge fracture behavior using uncoupled ductile fracture models. A fully integrated simulation framework for the edge fracture prediction is proposed with the shear-induced pre-damage considered. User-

A phenomenological ductile fracture initiation model is developed based on the assumption that onset of fracture is a limit state of void evolution followed by void coalescence at microscopic level. In the model, void grows in two typical deformation

Quenching is an important pipe production step that can also be responsible for geometric distortions in steel parts, depending on cooling heterogeneities, thermal contractions, and changes in the steel microstructure. The quenching stage generally l
