Аннотация: Abstract: This chapter deals with the simulation of the creep process and the effect of long-term strength of metals, notably, in both uniaxial and complex stress states. A description of a creep experiment and the simplest creep models are presented, i.e. the theory of steady creep, the theory of aging, the theory of flow, the theory of hardening. In creep processes simulation, a kinetic theory based on the introduction of structural parameters characterising the state of the metal at given time is widely used. Among such parameters, there is studied metal damage in the creep process, work of stresses on creep deformations (energy version), concentration of an aggressive medium in the metal. The coupled problem of creep and long tensile strength is also considered taking into account the mutual influence of damage accumulation and one-dimensional diffusion of the aggressive medium. The times to fracture are determined both in the presence of an aggressive medium and in the absence of one. A significant contribution of Soviet (Russian), European, American and Japanese scientists to the development of Continuum Damage Mechanics is highlighted. Keywords: kinetic theory, Continuum Damage Mechanics, creep, long-term strength, metals, scalar and vector damage parameters, fracture criterion, aggressive medium, diffusion.
