Abstract
The paper is devoted to the solution of the time-dependent periodic fracture problems for a cracked material with the allowance of contact between the cracks' faces. The variational formulation of the elastodynamic problem in terms of the actions generated by the contact displacement continuities on the cracks' faces including unilateral Signorini constraints and dry fraction are formulated.
The formulation leads to an infinite system of boundary integral inequalities, the finite section of which is then solved by an iterative procedure. For simple model problems, the corresponding numerical Galerkin approximations demonstrate the applicability of the method and also the clear difference to classical linear crack analysis without contact.
