摘要
A dynamic problem for an elastic space with a semi-infinite crack which suddenly begins to grow at a constant rate is considered. At the initial time, the crack faces at some distance from the crack tip are subjected to normal concentrated forces stretching the crack. The forces move along the crack faces at a speed different from that of the crack tip. The stress intensity factor is calculated. Various special cases are examined.
