We investigated influence of shape of clavicle reconciled plate of titanium alloy Ti-6Al-4V (Type A), which is one of materials for bone fixation device and another plate (Type B), which is changed shape with mechanical properties of them. In particular dynamic behavior of bone plate and properties of stress distribution under cyclic load or rotary force are measured with infrared radiation equipment. The results are as follows: Strain of Type B decreased in region fixed plate and elastic absorption energy increased, thus strain near fixed plate is less even under situation which rotary force angle changed dynamically for instance swinging arm.
