Plastics. Determination of fracture toughness (GIC and KIC). Linear elastic fracture mechanics (LEFM) approach1 Scope This document specifies the principles for determining the fracture toughness of plastics in the crack opening mode (mode I) under defined conditions. Two test methods with cracked specimens are defined, namely three point bending tests and compact specimen tensile tests in order to suit different types of equipment available or different types of material. The methods are suitable for use with the following range of materials, including their
