    Status: Open => Answered

Jan Stránský proposed the following answer:
Hi Liu,

1) there is a misprint in the thesis, the code is correct, i.e.
omega = 1 - (e0/kappa)*exp(-(kappa-e0)/ef)
for kappa=e0, damage should be 0

2) ok, this comment is clearly misleading and not true.. It is true for
linear damaged stress-strain law. but for default exponential one, epsF
controls the slope of the exponential but the exponential is never 0..

cheers
Jan
