The direct-current electrical potential difference (DCPD) method was added as a simultaneous alternative crack measurement to improve the chances of getting usable crack length predictions during J-R testing. The accuracy of the compliance measurement was less...

... that large amounts of compliance may greatly affect the shape of the observed load versus displacement trace and the shear yield stress determined from the trace. On the assumption that this would lead to shear punch properties that correlate even better with uniaxial tensile properties, a low compliance...

.... Further, the test method does not address other influences unique to a triaxial testing cell, namely frictional forces resulting from poorly manufactured or improperly designed seals, alignment issues and compliance. This paper addresses the sensitivities of the results due to appropriate...

... In previous research involving the use of shear punch test, it was understood that some compliance was present in the test frame and fixturing for a shear punch test, but it was assumed that this compliance would only affect the slope of the loading curve and not the perceived yield point...

... An attempt is made to track fatigue crack growth through cycle-by-cycle compliance estimates. The measurements are performed using continuous 16-bit data acquisition with multi-sample data averaging to reduce the influence of signal noise. With appropriate transducer ranging and data averaging...

... Using a finite element model to generate compliance values, stress intensity solutions were developed for an edge cracked T-section in tension. The finite element model was developed specifically for T-section geometries with thin web sections. Several T-section geometries were analyzed...

... A new experimental approach developed by fatigue crack growth rates can be determined for multiple specimens tested in series. This involves a geometry such that the response to cyclic loading in each specimen is mutually independent. Relationships between the stress intensity factor, compliance...
