Dynamic fracture mechanics with contact interaction at the crack edges
Dynamic fracture mechanics with contact interaction at the crack edges
- Engineering Analysis with Boundary Elements, 24(9), p.643-659, 2000 .
This paper deals with elastodynamic contact problems with unilateral restrictions and friction for bodies with cracks. General dynamic loading and a relevant case of harmonic loading are considered. The mathematical aspects of this problem are brie¯y discussed. The variational formulation of the problem, variational boundary inequalities and boundary functionals are used to solve it. The problems of a tension-compression plane harmonic wave interaction with one and two co-linear cracks of ®nite length with the allowance of unilateral contact interaction at the crack edges are solved. The in¯uence of the contact interaction between the crack edges on a stress intensity factor is investigated.
