ENERGY RELEASED DURING ARC CRACK PROPAGATION

摘要

The problem of circular arc cracks in a homogeneous medium is revisited. An unusual but simple method to calculate the energy change due to arc crack propagation along a circle is illustrated based on the earlier work of Sih and Liebowitz (1968). The limiting case of crack of angle 2 pi is shown to correspond with the problem of a circular hole in a large plate under remote loading.
