Mashayekhi, M., Ziaei-Rad, S., Parvizian, J., Nikbin, K., and Hadavinia, H., “Numerical Analysis of Damage Evolution in Ductile Solids”, Structure Integrity & Durability, Vol.1, No.1, 2005.

The continuum mechanical simulation of microstructural damage process is important in the study of ductile fracture mechanics. An essential feature in these analyses, is the strong influence of stress triaxiality ratio, ie the ratio of mean stress to equivalent stress, on the rate of damage growth. In this paper, finite element simulation of damage evolution and fracture initiation in ductile solids will be investigated. A fully coupled constitutive elastic-plastic-damage model has been implemented. The stress update ...
