G0301-6-3 Basic Study of Control of a Crack in Laminated Materials

Abstract

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.
