Study on Dynamic Destruction Behavior under Low Temperature Environment of Polymeric Material

摘要

The experiment for the destruction behavior of the polymeric material under the low temperature environment has not been increased. In this research, I think about use in an impact load situation under the low temperature environment so that I may evaluate the destruction behavior of the material. I artificially installed the crack in the test piece produced with the polycarbonate, used caustics method by me, and did three point bend test. And, I calculate the Dynamic stress intensity factor as an index that shows the destruction behavior, and aim to do the evaluation and the analysis of the influence on the dynamic destruction behavior under the low temperature environment.
