On the use of British standard 7910 option 1 failure assessment diagram to non-metallic materials

This paper provides a structural integrity assessment methodology for the analysis of non-metallic materials. The approach uses the British standard 7910 option 1 failure assessment diagram, originally proposed for the fracture-plastic collapse assessment of metallic materials. The methodology has been applied to 60 fracture specimens, combining 12 different materials and covering polymers, composites, and rocks. The results obtained validate the proposed assessment methodology and demonstrate its safety for the materials analysed here.
