S.O. Pyskunov, Yu.V Maksimyk, V.V. Valer

• The techniques of modeling of continual fracture process for spatial bodies under long-term static force loading condition in non-homogenous temperature field are presented. The scalar damage parameter is used to describe the material continual fracture process. A stress-strain problem solution made with semianalytic finite element method SFEMSFEM. Results of lifetime determination of responsible parts are presented.
