Study on Calculation Method of Fracture Parameters of the Tubular Based on 3D VCCT

Abstract:

Article Preview

The stress intensity factor (SIF) for tubular specimens were calculated based on virtual crack closure technique (VCCT). The effects of geomet rical factors (inner radius, wall thickness and relative crack length) and external loads on the SIF were analyzed, respectively, by use of the single-variable approach. Finally, an approximate formula for SIF of compact-tensile tubular specimens was obtained as all factors mentioned were considered, which was presented as a reference for the tubular engineering design.
