Abstract
An attempt to formulate the basic principles of mechanothermodynamics of systems is made. The notion of tribo-fatigue entropy generated in a mechanical system is introduced similarly to thermodynamic entropy governed by matter and energy exchange. Interrelation of motion, damage, and information is found. It is shown that motion generates new information in the system if its damageability index is non-zero. The information is positive if the system is hardened and negative if it softened. It leads one to perceiving the principal feature of interaction of irreversible damages (effective energies and entropy) generated by effects of different nature (mechanical loads, heat flows, etc.), viz. dialectic character of interaction. Two principles of thermodynamics are formulated.
