Abstract In recent years, there has been a growing interest in the use of additive manufacturing (AM) to fabricate metallic components with tailored microstructures and improved mechanical properties. One of the most promising techniques for the aero

Additive manufactured parts are subjected to intense thermal gradients and high temperature peaks which affect mechanical properties. Such thermal cycles can cause distortions, residual stresses and microstructural heterogeneities. Since the experime

The Bonora damage model was extended to account for shear-controlled damage. To this purpose, a new definition for the damage dissipation potential in which an explicit dependence on the third invariant of deviatoric stress was proposed. This express

The extended Bonora damage model was used to investigate joinability of materials in self-piercing riveting process. This updated model formulation accounts for void nucleation and growth process and shear-controlled damage which is critical for shea

A physical-based model for the flow stress of bcc metals is presented. Here, thermally activated and viscous drag regimes are considered. For the thermally activated component of the flow stress, the diffusion-controlled regime at elevated temperatur

Strain-based design for offshore pipeline requires a considerable experimental work aimed to determine the material fracture toughness and the effective strain capacity of pipe and welds. Continuum damage mechanics can be used to limit the experiment

Modeling ductile fracture in third stress invariant sensitive materials: Application to Al 2024-T351
Triaxiality alone is not sufficient to account for the role of stress state on ductility in materials that exhibit shear effects on fracture strain. For these materials, it has been proposed that ductility also depends on the third invariant of the s
