Effects of strain-rate and temperature on ductile damage and Fracture of metallic materials

Alexander Sancho Garcia
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 investigates the effects that temperature and strain-rate have on ductile damage from an experimental and a modelling point of view, and explores innovative...
