Revenko A. Effect of injection material creep on the effectiveness of renewal of damaged cracked structural elements strength.

Object of research - elastic bodies with cracks that filled by viscoelastic injection material. The purpose of research - to develop a mathematical model of bodies with cracks that filled viscoelastic materials. Set on the basis of its long-term strength of damaged structural elements, bearing capacity of which restored using injection technology. Methods of research - applied mathematical methods of solid mechanics, concepts and criteria of fracture mechanics of materials, integral Fourier and Laplace methods for solving integral equations. Theoretical and practical results - has developed the new mathematical model of deformation of elastic bodies with viscoelastic inclusion (crack filling) the basis for the engineering approach for calculating long-term strength of damaged structural elements of industrial buildings, restored for injection technologies. The results of the researches were used in SEEC "Techno-Resurs" for assessing the strength of the damaged building structures of long-term operation, bearing capacity of which are restored by the injection technologies.
