Plastics. Determination of mode I plane-strain crack-arrest toughness Ingestion-build-54484 Normally delivered externally and internally1 Scope This International Standard specifies a method for the determination of the plane strain crack arrest fracture toughness, Kla, of polymeric materials by using a side grooved, crack line wedge loaded compact tension specimen to obtain a rapid crack run arrest segment of flat tensile separation with a satisfactory crack front. This International Standard employs a static fracture analysis determination of the stress intensity factor at a short
