✦ Synopsis

The elastostatic plane problem of an infinite strip containing a transverse crack is considered. It is assumed that one side of the strip is perfectly bonded to a rigid support whereas the other side is free of traction. The problem is formulated in terms of a singular integral equation. Internal crack, edge crack, crack terminating at the rigid support, and completely broken strip cases are considered in some detail. The singular integral equation is solved numerically by employing collocation schemes developed by Erdogan, Gupta and Cook. The stress intensity factor, which may be regarded as the most important fracture parameter, and the crack surface displacement are calculated for various crack geometries and given in graphical form.
