Identification Damage Model for Thermomechanical Degradation of Ductile Heterogeneous Materials
International Journal of Applied Mechanics and Engineering, 2017 The failure of ductile materials subject to high thermal and mechanical loading rates is notably affected by material inertia. The mechanisms of fatigue-crack propagation are examined with particular emphasis on the similarities and differences between ...

Effects of strain-rate and temperature on ductile damage and Fracture of metallic materials [PDF]
, 2018 Ductile damage appears in metallic materials when they undergo sufficiently high plastic strain. It is caused by voids and produces degradation on the mechanical properties that eventually leads to the ductile fracture of the material. Like other properties, this behaviour is affected by the temperature and velocity of material deformation. This thesis

Effect of Ductile Damage Evolution in Sheet Metal Forming: Experimental and Numerical Investigations [PDF]
, 2010 The numerical simulation based on the Finite Element Method (FEM) is widely used in academic institutes and in the industry. It is a useful tool to predict many phenomena present in the classical manufacturing forming processes such as necking, fracture,

Experimental and numerical analysis of micromechanical damage in the punching process for High-Strength Low-Alloy steels [PDF]
, 2014 Sequential sheet metal forming processes can result in the accumulation of work hardening and damage effects in the workpiece material. The mechanical strength of the final component depends on the “evolution” of these two characteristics in the ...

The Evaluation of Varying Ductile Fracture Criteria for 3Cr20Ni10W2 Austenitic Heat-Resistant Alloy
Advances in Mechanical Engineering, 2013 Most bulk metal forming processes may be limited by ductile fracture, such as an internal or surface fracture developing in the workpiece. Finding a way to evaluate the ductile fracture criteria (DFC) and identify the relationships between damage ...
