Numerical Simulation of Damage to Fracture Transition in Metals Based on the Statistical Model of Mesodefect Evolution

Abstract:

A comprehensive approach, including statistical physics and thermodynamics is required in the modelling of phenomena underlying the processes of deformation and fracture of solids. This work is devoted to the description of the damage to fracture transition, using statistically based thermodynamic model of mesocracks and mesoshifts evolution. Numerical simulation of quasistatic tensile experiment of vanadium plate specimen illustrated the influence of bulk and shear defects on stress-strain state.
