Use Vumat to simulate the hot ductile fracture criterion of Freudenthal
Fri, 2013-06-07 22:24 - hongfengtl
Dear everybody,
I have just studied Abaqus and would like to use Vumat to simulate the hot ductile
fracture criterion of Freudenthal which have the equation: D=integral(0-fracture strain)
of (Smises stress)*d(strain). The fracture will be appear when I reach 1 unit.
Could you please show me how to write algorithm adding temperature to calculate (D) and
out put (D) in Vumat.
thanks you so much
I am looking forward to hearing from you

Freudenthal,VUMAT
hi,everybody,
Is it possible to get a copy of your UMAT/VUMAT subroutine for the hot ductile fracture criterion of Freudenthal in ABAQUS? It would be very helpful to my research.
Thank you,
hongfengtl
