Intelligent systems have recently received recognition for their ability to solve extremely
complicated and multidimensional problems. Artificial Neural Networks (ANN) has quite a lot …

Meso-damage mechanics differs from continuous damage mechanics, which pays more
attention to the evolution of meso-structure in materials. It combines physical and …

Developing an efficient non-associated plasticity criterion fully coupled with isotropic ductile
damage is the main contribution of the current research. Two ductile degradation functions …

Ultra-low cycle fatigue (ULCF) is a critical concern in the seismic design of steel structures
due to its adverse effects on the ductility and energy dissipation capacity of steel …

The stress-state and strain-rate dependent ductile fracture initiation property of S690 high-
strength steel is investigated in this study through experiments and simulations. A total of 14 …

Selective laser melting (SLM) is prevalent as one additive manufacturing (AM) technique to
produce metallic components. In this study, a modified GTN (Gurson-Tvergaard-Needleman) …

Abstract Selective Laser Melting (SLM) is one of the revolutionary additive manufacturing
(AM) technologies to produce metallic mechanical parts. To thoroughly understand the …

The most widely used phenomenological constitutive relation to model ductile failure of
structural metals at room temperature is based on the work of Gurson (1977) and has the …

This study presents the novel peridynamic constitutive relations formulated in order to
predict the plastic deformation and damage evolution in irradiated materials. The plastic …

Abstract Based on the Gurson-Tvergaard-Needleman (GTN) damage model, the damage
evolution and ductile fracture of 7075 aluminum alloy sheets during the tensile process were …
