Abstract
A loading device to be used in fracture experiment is presented. It's loading angle can be adjusted from $\small{-45^{\circ}}$ to $\small{105^{\circ}}$ at intervals of $\small{15^{\circ}}$ for a CTS ( compact tension-shear) specimen, so that it is to be useful to measure mixed mode toughness. The equations to give the $\small{K_ I}$, $\small{K_ I1}$ and J-integral for the experiment are evluated though finite elemetn analysis in which the loading procedure is simulated and the behaviors of the specimen such as load-displacement curve are estimated. In the course of the evaluation the values $\small{K_ I}$, $\small{K_ I1}$ and J-integral calculated through recentrly released numerical methods are employed as the reference ones.
