DAMAGE PARAMETERS IDENTIFICATION OF ALUMINUM ALLOY BASED ON ANISOTROPIC GTN MODEL
In this paper,the GTN damage model coupled with anisotropic yield criteria were implemented by establishing a user defined subroutine under the framework of LS-DYNA/Explicit finite element code. Taking 6016 aluminum alloy as the research object,the GTN damage parameters were identified by comparing...
