Fracture dynamics with crack edges contact interaction

In this paper we consider classical and variational of fracture dynamic problems with taking into account a contact interaction of the crack edges. An algorithm for the solution of the elastodynamic contact problem with unilateral constrain has been developed. It arises from the boundary variational principle of elastodynamics for bodies with cracks and unilateral constrains on their sides. Some numerical results are presented for 3-D elastodynamic unilateral contact problem for bodies with cracks. Key-Words: Fracture, elastodynamics, unilateral contact, variational principle, stress intensity factor.
