| Abstract: | This paper presents an effective modulus method in 2-dimensional creep damage problems. An evolution equation of damage is proposed based upon the thermodynamic theory. Nonlinear finite element analysis are given for both effecfive modulus and effective strese models. Two models are compaled numerically. |

| Keywords: | creep damage effective modulus effective stress finite element difference |
