Abstract
In this article some results concerning problems in the fracture dynamics of elastic bodies with allowance for unilateral crack edge contact interaction with friction are presented. A formulation has been made of the elastodynamic contact problem with unilateral restrictions for bodies with cracks under arbitrary dynamic loading. A specific case of harmonic loading has also been considered. The boundary integral equations (BIE) method in a Laplace transform and frequency domains has been used as a solution for the elastodynamic problem for bodies with cracks. Singularities of the kernels in these integral equations have been studied. Regularization methods for the potentials with weakly singular, singular and hypersingular kernels have been considered. Several algorithms for the solution of the elastodynamic unilateral contact problem for bodies with cracks have been elaborated. Numerical methods have been elaborated for the solution to elastodynamic contact problems with unilateral restrictions and friction for bodies with cracks. Some problems for plane harmonic wave propagation in space with plane cracks with allowance for unilateral contact interaction of the crack edges have been solved. Quantitative and qualitative effects caused by contact interaction of the crack edges have been investigated.
