Highlights
A deformable solid is presented as a physical macroscopic thermomechanical rheological system formed by waves - quasiparticles. The dependences and universal physical parameters of the strength of materials are theoretically substantiated; on their basis, an algorithm and computer method for calculating the standard mechanical indicators are developed: proportionality limit, ultimate strength, fatigue, etc. Methods for analytical assessment of universal physical parameters of material strength (boundary conditions of the equation).The method is based on physical analysis of the results of standard tensile tests to fracture ISO6892-84, analysis of kinetic indentation data ISO 14577-1: 2002.
