摘要
材料的力学性能是指材料抵抗各种外加载荷的能力,包括:弹性和刚度、强度、塑性、硬度、冲击韧度、断裂韧度及疲劳强度等。通过介绍金属材料和非金属材料的基本力学性能及测定方法,用作设计和选材的依据。
The mechanical properties of materials refer to the ability of materials to resist various external loads,including elasticity and stiffness,strength,plasticity,hardness,impact toughness,fracture toughness and fatigue strength. The basic mechanical properties and measurement methods of metal materials and non- metallic materials were made for basis of the design and selection.
