1. Mechanical Properties | 力学性能术语
Understanding how materials behave under load starts with core mechanical property terms. These properties guide material selection in design.
理解材料在载荷下的行为始于核心力学性能术语。这些性能指导设计中的材料选型。
Hardness – resistance to localised indentation or scratching, often measured by Brinell or Rockwell tests. Think ‘hard enamel’ coating to recall that hardness protects surfaces.
硬度 – 抵抗局部压痕或划痕的能力，常用布氏或洛氏试验测量。联想 ‘硬珐琅’ 涂层记住硬度保护表面。
Toughness – ability to absorb energy up to fracture, blending strength and ductility. Imagine a tough car bumper that crumples without breaking.
韧性 – 断裂前吸收能量的能力，结合强度与延展性。想象韧性汽车保险杠能皱缩却不断裂。
