Abstract

It is well-known that the parameters of dynamic fracture mechanics depend not only on dimensions, loading and boundary conditions but also on the dynamic crack propagation velocity. Because the measurement of dynamic crack propagation velocity measuring device which can easily be expanded without modification is proposed in this report. it was found that the experimentally determined dynamic crack propagation velocity agreed well with those from other investigations in some polymers such as PMMA. Homalite-100 and Epoxy.

본 연구에서는 디지틀식 균열속도 측정장치를 보완, 확장시켜 몇몇 고분자 (polymer)재료에 있어서의 동적 균열전파속도를 측정하였으며, 다른 연구자들의 실험 데이터와 비교하였다.
