Proposed Standard Arc-Bend Chord-Support Fracture Toughness Specimens and Expressions

CODEN: JTEVAB

Abstract

Collocation and finite element calculations and limit solutions were used to propose standard geometries and K expressions for measuring fracture toughness with arc-bend chord-support specimens. Polynomial expressions for K were determined for a wide range of crack lengths and for two span-to-depth ratios. The fracture toughnesses of steel and aluminum alloys were measured using the proposed methods and compared with results from existing standard methods.
