In this study, clavicle reconciled plates of titanium alloy are examined for mechanical properties. In particular, strain curves are measured on axial direction of bone plate, and properties of stress distribution are observed by infrared rays method under dynamic compression. The results obtained are as follows: 1) Shape of hook and plate effects on increase of strain under dynamic compressive load F_<max>=147N. 2) Shape of hook and plate effects on stress distribution. 3) Infrared rays method is applicable to relative evaluation on mechanical properties of biological materials.
