| 摘 要： | The K field parameters of K1, KI, and *ox at the crack tip associated with crack high-velocity curving of epoxy resin specimen under impact tension are determined. The parameters obtained are used to construct the theoretical isochromatic fringe patterns fitting the experimental data. The curves of dynamic relation between stress intensity factor and crack length is also given.
