The opposite faces of existing cracks interact with each other under deformation, affecting significantly the stress and strain fields. Unfortunately, due to substantial complications in solution researchers almost always neglect the contact interaction of crack faces in spite of its evident significance.
In order to take the contact interaction of crack faces into account we assume there is no interpenetration of the opposite crack faces and the contact force is unilateral. Thus the Signorini constraints are imposed for normal components of displacements and forces. We also assume that the contact interaction satisfies the Coulomb friction law. The solution is refined during the iteration process until the distribution of physical values satisfy the contact constraints. The results are compared with those obtained without allowance for the contact interaction.
