Experimental Investigation of Mode Ⅰ Fracture Toughness of Adhesives under Impact Loading Conditions

摘要

A falling wedge test machine, which can generate enough impact loading for the DCB tests with structural adhesives, were manufactured. The DCB tests with specimens bonded with a structural adhesive were carried out and the fracture toughness was calculated. The applicability of the machine to the impact DCB tests has been investigated.
