CONTACT PROBLEMS FOR ELASTIC SOLIDS WITH INITIAL STRESSES (ELASTIC DIES) (REVIEW)

The problem of load transfer in structures and machine components by means of their contact interaction plays an important role in modern technology and involves a wide range of examination of fundamental and applied nature. At present, one of the aspects of this problem is associated with a qualitatively new approach: consideration of the effect of the initial stresses in interacting solids (or in one of them) on the characteristics of their stress-strain state. A sufficiently representative number of investigations in which these aspects were taken into account were carried out into contact interaction of solids with initial stresses and rigid dies [1]. However, real solids situated in combined contact are elastic. Although the stiffness of one of them can greatly exceed the stiffness of the other solid, engineering practice is more interested in the stress-strain state of both solids. The aim of this work was to describe comprehensively and classify the investigations carried out into the theory of contact interaction between prestressed solids and elastic dies (straps).
