ActivePlastics—Determination of fracture toughness (GIC and KIC)—Linear elastic fracture mechanics (LEFM) approach
塑料 断裂韧性（GIC和KIC）的测定 线弹性断裂力学（LEFM）法
Application Summary AI generated
This standard specifies the linear elastic fracture mechanics (LEFM) method for determining the fracture toughness of plastics, specifically the critical strain energy release rate (GIC) and the critical stress intensity factor (KIC). It is applied in material testing and quality control for rigid plastics and polymer composites used in engineering components, such as automotive parts, aerospace structures, and consumer goods, where resistance to crack propagation is critical for safety and performance.
