Analysis of Some Fracture Mechanics Test Procedures for Defence Research Applications

Abstract

Analysis has been presented of six fracture mechanics specimens and associated test procedures. Stress intensity factor results, and displacement results in some cases, have been compared for each specimen with numerical results and limit solutions from the literature. The specimens and test procedures analyzed are a compact specimen for general fracture testing; a crack arrest compact specimen, a modified compact specimen for brittle coating tests, a bend specimen for stress-corrosion cracking tests, a round bar bend specimen, and a tensile panel for composite material tests. Comparison with literature results was used to draw conclusions regarding accuracy of stress intensity factor and displacement relations for the specimens. Keywords: Tensile properties; Australia.
