hi, everybody
i am going to simulate crack propagate by ABAQUS, but i haven't used ABAQUS before.
now i have two problems:
1) can abaqus calculate the velocity of crack advancing?
2)FGM(functionally graded materials ). material property varies at
different position,such as density ,modulus, possion ration. can
abaqus deal with this problem by umat .
thanks.
