Purpose of work is formulation of new fundamental equations mechanics. Research methods are numeral methods of calculation of nonlinear deformation and damage. Equations of the state of anisotropic materials and laws of accumulation of damage are developed on the basis of tensor measures of damage in the conditions of nonisothermal creep. On the basis of continual mechanics of damage the process of the autofrettage thick-walled cylinders is explored. Mathematical models are developed, methods and the numeral calculations of heat conductivity, termoelasticity, plasticity and creep of fibred composite are done. For plastic properties of composite a continual mathematical model and method of decision of equalizations, based on the method of resilient decisions and finite-element method is developed. Research of the tensely-deformed state of sliding thrust bearing was conducted. The mathematical models and programming software is developed for the analysis of processes of relaxation of remaining tensions at vibration treatment of constructions. All got results have a scientific novelty, and the developed algorithms and programming software are used in practical engineering researches of elements of constructions.
