Fundamental Laws of the Ultimate State of Objects at the Combined Effects of Multi-Parameter Power Factors and Thermodynamic Environment. Part II

Abstract

It is a survey-analytical article, which describes a number of criteria of limit states (LS) of complex objects and identifies methods to measure all the parameters necessary for it practical use. It presents the energy theory of LS of tribo-fatigue and mechanothermodynamical (MTD) systems, taking into account the interaction dialectics of efficient energies and therefore irreversible damages under fatigue loading, friction and temperature influence. The fundamental laws of the LS at the combined effects of multi-parameter power factors and the environment are analysed. The experimentally grounded (over 600 experimental results) fundamental MTD function of forecast evaluation of different LS (static, fatigue, contact fracture) for pure metals, non-ferrous alloys, constructional steels and polymer materials is presented.
