摘要

This paper presents an investigation how fracture energy, as a CZM parameter, used to describe fracture process, affects the behaviour of TDCB bonded joints subjected to a range of test rates. It was found that for the stable fracture behaviour, i.e. 'Type 1' and 'Type 4', predictions were very accurate using all the 'profiles' which were selected to describe the relationship between G_(Ic) and the average crack velocity. In fact, similar results can be obtained using both constant and rate-dependent fracture energy values.
