Finite element analysis procedures are utilized to provide theoretical calibration curves for the electrical potential crack-monitoring system as applied to single-edge-notch (SEN) and compact tension (CT) fracture specimens. The results are compared to existing calibrations for such test piece geom

The potential drop method as used in fatigue and fracture toughness testing has been applied to tests on COD specimens. These tests showed that providing electrical stability is maintained, the method can be used to detect the onset of ductile crack growth. Initial plastic deformation (in absence of
The use of the finite element method to calculate electrical potential drop vs crack extension calibration curves for fracture mechanics test specimens is investigated. The influence of finite element mesh size and the use of singular elements at the crack tip are considered. Also, some of the detai
