The double column made of dissimilar materials about the experimental analysis is reported a little. The author experimented about a double column with the dissimilar material o is used in various fields. When the boundary of this double column is dynamically seen, a discontinuous joint field side is a singularity point with a very big stress. The crack occurs easily in phase boundary of the different kind material for that reason. The stress analysis of vicinity at the edge of the crack to which destruction is expected to evaluate this in strength is necessary. The stress intensity factor is effective to clarify the behavior of the states when the crack of a double column exists in the phase boundary at the vicinity of the crack. This research is a photoelasticity method and due to the coustics method with stress freezing method and was got the good result.
