✦ Synopsis
A&r&-Using solutions based on fracture mechanics, the authors have developed a technique referred to as the "crack-compliance method" to measure residual stresses. In the present paper the method is applied to the measurement of residual stresses either at the toe of a weld joining a bracket to a plate or at the toe of a fillet weld between two plates. It is shown that the crack compliant: functions for a wide range of configurations may be obtained by combining the solutions for an edged-cracked plate with a simple finite element computation. Experimental results are presented for a specimen which simulates the attachment of a bracket to the wall of a nuclear reactor pressure vessel.
