Hi...
if i have the equation as below
σ(n+1) = σ (n) +delta(σ)
if i get the initial stress, σ (n) and the differential stress, delta(σ), ist i need the call the (KEY . EQ. 11) THEN ....
or i need to make the full stiffness matrix and then
do i = 1, ntens
stress (i) = .......
ur help highly appreciated.
