| Abstract: | The dynamic stress intensity factor of a three-dimensional elliptic crack under impact loading is determined with the finite
element method. The computation results can take into account the influence of time and the ratio of the wave speeds on the
stress intensity factor. The present method is suitable not only for three-dimensional dynamic crack, but also for three-dimensional
dynamic contact.
