Body straining and fracture in terms of the kinetic structure-and-energy failure theory

Some definitions and relationships for new physical molar quantities such as molar energy, molar volume of quasi-particles, rate of micro-fracture accumulation, etc., are stated in terms of the kinetic structure-and-fracture theory for the strained body. Molar kinetic parameters of the strained body are revealed as physical characteristics of material strength and durability. For a particular case physical molar functions and its derivatives are given analytically; such functions define irreversible deformation in rates and absolute values, formation of dislocations (damage), free microscopic and macroscopic surfaces, build-up heat and time of macroscopic failure of the strained body. The utilization of the resultant relationships helped to estimate numerically the failure and fatigue limits, material creep rate under different temperatures and loading. These results correspond with experimental data.
