Once the metallic material under deformation lead to the nucleation, growth and coalescence of voids that it is root of ductile damage.The main objective of this work was enhancement of micro-void growth-bas Enhancement of void growth model for the anisotropic ductile metal ed damage model to predict ductile fracture behavior of sheet aluminum alloys, typical for civil structures with anisotropic properties and their implEnhancement of void growth model for the anisotropic ductile metal
ementation in user-defined material subroutine (VƯMAT). The explicit finite element code has been chosen for implementation of new material models. CoVIETNAM NATIONAL UNIVERSITY - HO CHI MINH CITYHO CHI MINH CITY I ND ERSITY OF TECHNOLOGYNGUYỄN HỮU HÀOENHANCEMENT OF VOID GROWTH MODEL FOR THE ANISOTR Enhancement of void growth model for the anisotropic ductile metal e.The second important aspect of this dissertation was performance of tensile experiments in three different orientations of materials for identification of mechanical behavior of high strength sheet aluminum alloys AA6061-T6. The results from these tests allowed derivation of material constants for Enhancement of void growth model for the anisotropic ductile metal constitutive models and help to have a better understanding of anisotropic material behavior. The tensile tests were also used to validate the implemEnhancement of void growth model for the anisotropic ductile metal

The validation of the constitutive models has been performed by numerical simulations of tensile, deep drawing and Nakai ima tests.
