The kinetic theory of the idealized gas and vector field theory are used to interpret the ideal-gas law as wave equation for microscopic motion continuity of energy waves subject to thermal fluctuations within gas elementary volumes. Definitions for molar volume of idealized energy particles, molar energy potential, local molar capacity of the idealized gaseous fluid are stated.

The generalized physical model is built for the microscopic fracture of atomic bonds, macroscopic irreversible forming and failure of the strained body conglomerate. The process is presented as a result of idealized cooperative atom bonds failure and accumulation of irreversible elementary shifting within idealized structural units of the strained body. Physical concepts for molar volume of strength quasi-particles, molar energy, and molar capacity of the strained body strength quasi-particle failure are established. The relationships between molar capacity of the strained body strength quasi-particle failure and stresses, strains, timing and structure-physics parameters of the medium is analytically determined.

The nonlinear differential constitutive equation for molar energy of the strained body is obtained. It helps to define physical conditions, parameters and time to macroscopic fracture under non-stationary loading. Solution of equation brought forth the analytic function of material structural parameter, Zurkov durability formula and empirical relationships for properties of structural variation irreversibility. Experimentally and theoretically sound kinetic structure-and-energy law is stated for the uniaxial and combined stress state of the strained body.

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.
