Dynamic Shear Response of Soft Tissue Materials

During exercise, an athlete’s knee could be tested under heavy loading repeatedly. In this study, dynamic shear tests of knee soft tissue under high strain rate were performed. Porcine knee tissues were prepared as the test sample. The dynamic strength of meniscus and cartilage tissues were examined at six different locations and orientations. Modified Hopkinson bar were utilized to perform the experiments. Modifications were made on incident bar and transmission bar to make sure that specimens receive force evenly and for easier shear test process. The research finding will assist the future researches on knee dynamics and soft tissues restoration.
