Fracture Toughness Testing

Element提供广泛的断裂韧性和力学测试服务，以帮助您估计组件的寿命, reduce costly repairs, improve designs, and prolong a component’s life expectancy.

Fracture toughness testing is a mechanical test method 用于确定材料内部启动和导致失效所需的能量. It can also be used in conjunction with fatigue testing, corrosion testing, and elevated temperatures 确定材料在不同条件下的使用寿命.
