Recently, laminated materials are used in many fields such as vehicles. Material combination is effective to control fracture. Laminated materials are expected to protect fracture. When a crack appear in it and develop, it may be able to stop crack developing at interface. In this study, we did impact three-point bending test and determined dynamic stress intensity factor useing caustics method and high speed camera. Result shows that material combinations are enable to control fracture.
