DUCTILE DAMAGE INITIATION AND EVOLUTION (INIEVO) IN OPTISTRUCT IMPLICIT-EXPLICIT
The INIEVO criterion allows a two-step failure approach, divided into an initiation phase, in which damage has no effect on the stress computation, and a damage evolution phase, in which a stress softening can be generated. Ductile material behavior can be modelled in Optistruct with Damage Initiation DMGINI, and Damage…
