Abstract
Many papers [1–5] are devoted to problems of load-transfer from deformed thin-walled elements to massive bodies. There are also the papers on studying the interaction of thin-walled elements and cracks, which are located in massive bodies [6–8]. The problem of load-transfer from deformed thin inclusions to infinite visco-elastic plate with slits, which are made of ageing materials, is considered. Taking into account that the inclusions are in uniaxial stress state, the governing system of equations for stated problem as a system of two-dimensional singular integral-differential equations with respect to jump-function of shear stresses, acting on edges of inclusions, and derivative of function for opening of slit. Using trapezium method for calculation of time integrals and taking into account the behavior at end- points of inclusions and slits, the solution of governing system is built by the numerical-analytical method of discrete singularities. In special case the numerical analysis of stated problem is fulfilled and the behavior of contact stresses, cracks’ openings and intensity coefficients of destructive stresses depending on time characteristics are revealed.
