Recently, thermoelectric material that converts heat into electricity is remarkable as the energy conversion material of heat and electricity. There is a possibility that such a thermoelectric material can be widely applied to the energy and medical field such as thermoelectric power generation using vehicle exhaust emission abolition heat of car, power supply for space satellite and clinical thermometers, etc. When thermoelectric material is joined to other materials and external force and heat are applied, singular stress field is generated in the corner junction of the body junction, causing a decrease in the strength of the material, there is reliability may be lost. In the present study, it was formulated to analyze the order of singularity at the vertex in three dimension thermoelectric material by the eigenvalue analysis based on the finite element method.
