MULTIPLE INNER CRACK GROWTH SIMULATION USING S-VERSION FEM

摘要

Growth behaviors of multiple inner cracks, which are located near to structure surface, are simulated using S-FEM. Coalescence of cracks occurs before penetration to surface in some condition. In other condition, penetration occurs before coalescence. By changing relative locations of two inner cracks, these phenomena are observed, and criteria for coalescence and penetration are discussed.
