傾斜衝突下の予き裂三点曲げ破壊試験片のき裂進展挙動解析

抄録

Some dynamic fracture are caused by high speed collision. If defect is appeared near impact zone, crack propagation behavior from the defect depend on some factor about the collision. In this study, authors focused dynamic three point bending fracture experiments using sharp edge striker. Small slant of striker is assumed in numerical simulations. Dependence of fracture behavior on the slant angle of striker are discussed based on dynamic J integral distribution along crack tip front.
