Hello,
I want to input material properties of AlMg3 alloy for hydroforming process. I have put the data points from the stress-strain curve in L direction in mechanical > plasticity > plastic . I have the value of R0,R45,R90 so i can obtain R11,R22,R33,R12 and put in sub-options > potential.
The material response is assumed to be normally anisotropic.The average values of the yield stress, ultimate tensile strength, Lankford ratio (or anisotropy parameter) R were 80MPa, 205MPa, 0.67 The material is assumed to obey Hill’s normally anisotropic plasticity theory with R=0.67
Is this the correct approach or do I need to input only the data points?
Thank you in advance.
