To analyze the fracture behavior of multiple cracks and their effect, researchers did some bending tests. However, tests could not be stopped to observe details of crack propagation path and interaction due to the limitation of numbers of the test. Therefore, from test geometries in the previous studies, non-aligned twin cracked pipe simulation was performed by applying the FE damage model which based on stress modified fracture strain. In this paper, crack behaviors and the interaction effects between non-aligned twin cracks on the maximum bending stress were investigated.
