Abstract
Fatigue crack growth under mixed mode loading conditions is simulated using S FEM. By using S-FEM technique, only local mesh should be re meshed and it becomes easy to simulate crack growth. By combining with re' meshing technique, local mesh is re-meshed automatically, and curved crack path is modeled easily. In the previous paper, basic problems were solved, and availability of this method was verified. In this paper, interaction of two parallel cracks with differont level is studied. By changing relative locations of two cracks, totally 161 cases are solved, and results are summarized by normalized form. It is shown that there is a clear area in which interaction between two cracks is not neglected. A new criterion to evaluate interaction effect between two parallel cracks is proposed.
