  • GS26 Impact Test for Evaluation of Deformation Characteristics of Soft Materials and Tissues at Subsonic Level

抄録

Impact test at subsonic level is developed and applied to the evaluation of deformation behavior of soft materials such as biological soft tissue. The deformation resistance modulus of quasi-static examination is compared with that of the impact test at subsonic level. The results of the impact test at subsonic level are much higher than that of quasi-static examination in all materials. The material emulating a chicken are almost equivalent with a chicken breast in terms of deformation resistance modulus and behavior of the destruction. As a result of impact test simulation using the viscoelastic model applied deformation characteristic of chicken breast, the behavior of specimen crushed surface at the moment of ball collision is confirmed.
