In order to study on strain testing method and mechanical mechanism of human bone damage,a strain testing system suitable for 40％ glass fiber reinforced polyphenylene sulfide(PPS)simulated bone is established,and the calibration test of testing system is conducted. The principle and technical indicators of each component of the test system are analyzed. The universal testing machine is used to load the test-piece for many times,and the static calibration parameters of the strain test system under three working conditions of tension,compression and three-point bending are analyzed. The results show that the PPS simulated bone strain test method can effectively characterize the strain situation in the bone damage. This study can provide a reference for the test study of bone injury in trauma ballistics and pathology.
