UpcomingPlastics—Determination of fracture toughness—J-R curves approach
塑料 断裂韧性的测定 J-R曲线法
Application Summary AI generated
This standard specifies the method for determining the fracture toughness of plastics using the J-R curve approach, which measures the material's resistance to crack initiation and stable crack growth. It is applied in material testing and quality control for plastic products used in structural applications, such as automotive components, packaging, and piping systems, where resistance to fracture under load is critical. The standard is particularly relevant for engineers and procurement professionals evaluating plastic materials for high-stress or safety-critical environments.
