Abstract

The comparison of recent calculations for the propagation of axial cracks in pressurized pipes with experimental data suggests that the crack growth is governed by the inertia of the separating parts. In order to study the validity of this conclusion for other configurations, the basic problem of a tensile plate was analyzed and the results reported herein. Numerical results for different plate heights, widths and initial crack lengths in conjunction with the CTOA criterion, suggest that the principle of inertial control is valid for a wide variety of crack extension histories.
