On the Development of Mechanothermodynamics as a New Branch of Physics

Abstract

This paper aims to substantiate and formulate the main principles of the physical discipline-mechanothermodynamics that unites Newtonian mechanics and thermodynamics. Its principles are based on using entropy as a bridge between mechanics and thermodynamics. Mechanothermodynamics combines two branches of physics, mechanics and thermodynamics, to take a fresh look at the evolution of complex systems. The analysis of more than 600 experimental results allowed for determining a unified mechanothermodynamical function of limiting states (critical according to damageability) of polymers and metals. They are also known as fatigue fracture entropy states.

Keywords: Mechanothermodynamics; tribo-fatigue entropy; wear-fatigue damage; stress-strain state; limiting state; damage state; dangerous volume; interaction; irreversible damage
