Dear Users,
I am writing an umat for Progressive Damage modeling.When
i compiled my umat,its working good but the onlyproblem it shows is the strains are getting zero .
I tried to change my input file many number of times but still it shows 0 strains
And here is my umat where i calculated the strains
DO I = 1, NTENS
STRANT(I) = STRAN(I) + DSTRAN(I)
END DO
DO I=1,NTENS
write(7,*) 'STRAINS ARE'
write(7,*) STRANT(I)
END DO
c
c PRESENT STRESSES FOR THE MATERIAL WHEN NO DAMAGE
DO I= 1, NTENS
STRESS(I)=0
DO J = 1, NTENS
STRESS(I)= STRESS(I)+CFULL(I,J)*STRANT(J)
END DO
END DO
Can anyone knows what is the problem
Thanks
Rajesh
