New classes of contact problems for elastic infinite and finite bodies with textured and irregular surfaces have been solved taking into account the deformations caused by heat and mass transfer processes. The contact and thermoelastic behavior of structures with a regular array of intersurface gaps and interfacial cracks in the presence of a fluid filler under conditions of stick and frictional slip has been analyzed. Local contact parameters in the vicinity of the microregularities and the effective characteristics of textured bodies and bimaterials with interfacial cracks have been determined. The thermoelastic state of cylindrical bodies with variable in time boundary parameters under the action of volume and surface heat sources has been studied. The thermal fields and stresses in shells with piecewise constant heat transfer coefficients have been determined. The contact phenomena associated with interaction between bodies with surface irregularities under diffusive filling of interface gaps have been investigated. The results of the investigations are important for geophysics, aircraft and engineering industries, biomechanics, tribology and energetics. Product Description popup.authors Євтушенко О.О.
