This article deals with modelling of creep fracture and fatigue of metals. A short description of the physical mechanisms of creep phenomena is given. Developed thermodynamically consistent material model is described in detail. The material parameters are calibrated for the 7CrMoVTiB10-10 steel in the temperature range 500-600 oC. The model is implemented as a user subroutine in the commercial finite element code ANSYS.
