A mixed explicit‐implicit numerical integration algorithm for creep stress analysis is presented in this paper. This method allows simultaneously use of, and thus benefit from, both these integration schemes. The continuum damage constitutive model is also implemented in this algorithm. The present method is suitable for the prediction of creep crack growth in solids using the continuum damage approach. Numerical examples using different constitutive equations have been included to demonstrate the high efficiency of the proposed algorithm.
