Stress Intensity Calibration of a Ring Specimen Using a Finite Element Technique

Abstract

A finite element technique has been used to determine the stress intensity at the tip of a bore crack in a cylindrical fracture specimen. This technical note describes the detailed input for the computer programs which perform the stress analyses. Much of the preparatory work involves generating a suitable mesh of elements which represents the elastic properties of the specimen. The constraints which are imposed on the mesh geometry are described. Keywords: Crack propagation, Stress analysis, Australia, DISMAL (Computer program), DISMAL(Different Measurement Analysis).
