Long-term strength criterion based on V. V. Novozhilov concept of loosening

Abstract

The kinetic equation for the rate of creep parameter of continuity and long-term strength criterion was formulated on the basis of experimental studies results of density changes in high-temperature creep of metals and taking into account the law of conservation of mass. A comparative analysis of obtained solutions with the relevant results was made according to Kachanova-Rabotnova concept of damage.
