Research Abstract

Experiments on removing temperature at an interface of bonded joint have been made for estimating the joint strength of dissimilar materials and the effect of specimen sized on the strength. The joint was made by a resin curing on a steel. The removing temperature was measured by a thermo-couple and a visual observation. It is shown from the experimental results that the removing temperature becomes constant when the width of resin is greater than 8 times as long as the thickness of resin and the thickness of steel is greater than twice as long as that of resin. The energy release rate g -value of a virtual crack length, which exists within the singular field in the vicinity of the corner caused by a combination of dissimilar materials and a wedge angle, is useful parameter for predicting the removing temperature.
