Pidstryhach of the National Academy of Sciences of Ukraine popup.description2 The mathematical models of contact interaction between bodies with surface inhomogeneities, continuous and discrete coatings, and interface defects have been developed taking into account the force and heat transfer through the filler of interface gaps, capillary and dry adhesion, local frictional slip, and changes of boundary parameters during loading. New classes of contact problems of the theory of elasticity, thermal conductivity, and thermoelasticity for infinite and finite bodies with surface irregularities and discrete coatings were solved. The effect of adhesive and capillary phenomena on the contact interaction of bodies with conforming surfaces was studied. The contact of stresses in the bodies with single and periodically located discrete elastic coatings was examined. The influence of variable thermal resistance and gas pressure in intercontact gaps on the contact behavior of bodies, taking into account frictional slip, and bimaterial bodies with interfacial cracks was studied. Effective contact parameters of joints with load-varying interfacial characteristics were investigated. The thermal rectification was analyzed for bodies with periodically arranged surface gaps and interface cracks. The results of the investigations are important for geophysics, aircraft and engineering industries, biomechanics, tribology and energetics.   Product Description popup.authors Malanchuk Nataliya I Martynyak Rostyslav M Serednytska Khrystyna I Slobodian Bogdan S Khapko Bohdan S popup.nrat_date 2021-02-09 Close
