Crack width and plastic strain
Step 2. Calculate crack strain eps_cr which does not include elastic strain.
eps_cr(i) = eps_nst(i)-sig_nst(i)/E
where, i = 1, 2 for two dimensional
i = 1, 2, 3 for three dimensional
Step 3. Calculate crack width, cwitdh.
cwidth(i) = eps_cr(i)*char_len
where, char_len is the characteristic length of the element
i = nn, ns, nt.
