Comprehensive Guide to ISO 21459 Fracture Toughness of Metallic Materials Laboratory Testing Service
Provided by Eurolab
ISO 21459 is a widely accepted international standard for determining the fracture toughness of metallic materials. This standard is part of the ISO/TC 164, Mechanical testing of metals, and is used to evaluate the ability of metallic materials to resist crack growth and propagation.
The standard is based on the principles of linear elastic fracture mechanics (LEFM) and is applicable to a wide range of metallic materials, including alloys, steels, titanium, and other ferrous and non-ferrous metals. The test method involves determining the critical stress intensity factor (KIC) at which a crack in the material will propagate.
