摘要
An analytical micromechanics model is proposed to describe the influence and interaction. of fatigue and creep. A recently proposed micromechanics model for fatigue crack growth is employed and further developed. The calculated dc/dN curves exhibit significant features of fatigue-creep interaction that is in general agreement with the experimental observation.
