MECHANICAL PROPERTIES OF METALS
Mechanical properties are the characteristic responses of a material to applied forces. These properties fall into five broad categories: strength, hardness, elasticity, ductility, and toughness.
Strength is the ability of a metal to resist applied forces.
Strength properties are commonly referred to as tensile strength, bending strength, compressive strength, torsional strength, shear strength and fatigue strength.
Tensile strength is that property which resists forces acting to pull the metal apart. It is one of the most important factors in the evaluation of a metal.
Compressive strength is the ability of a material to resist being crushed. Compression is the opposite of tension with respect to the direction of the applied load. Most metals have high tensile strength and high compressive strength. However, brittle materials such as cast iron have high compressive strength but only a moderate tensile strength.
Bending strength is that quality which resists forces from causing a member to bend or deflect in the direction in which the load is applied. Actually a bending stress is a combination of tensile and compressive stresses.
Torsional strength is the ability of a metal to withstand forces that cause a member to twist.

MECHANICAL PROPERTIES OF METALS
金属的机械性能

Mechanical properties are the characteristic responses of a material to applied forces. These properties fall into five broad categories: strength, hardness, elasticity, ductility, and toughness.
金属的机械性能是金属受到外力作用时所表现出来的特征。这些性能主要分为五类：强度，硬度，弹性，塑性，韧性。

Strength is the ability of a metal to resist applied forces.
强度是金属承受外加力的能力。

Strength properties are commonly referred to as tensile strength, bending strength, compressive strength, torsional strength, shear strength and fatigue strength.
强度性能一般涉及到抗张强度，弯曲强度，耐压强度，抗扭强度，切变强度和疲劳强度。

Tensile strength is that property which resists forces acting to pull the metal apart. It is one of the most important factors in the evaluation of a metal.
抗张强度是金属抵抗被分离的能力（性能）。是评价金属的重要因素之一。

Compressive strength is the ability of a material to resist being crushed. Compression is the opposite of tension with respect to the direction of the applied load. Most metals have high tensile strength and high compressive strength. However, brittle materials such as cast iron have high compressive strength but only a moderate tensile strength.
耐压强度是金属抵抗被压碎的能力（性能）。压力是张力的反方向外加负载。大部分金属具有较高的抗张强度和较高的耐压强度。但是，像铸铁这种脆金属虽有较高的耐压强度，却只有较中等的抗张强度。

Bending strength is that quality which resists forces from causing a member to bend or deflect in the direction in which the load is applied. Actually a bending stress is a combination of tensile and compressive stresses.
弯曲强度是金属抵抗所受负载方向的弯曲和倾斜的能力（性能）。实际上弯曲应力是压力和张力的综合。

Torsional strength is the ability of a metal to withstand forces that cause a member to twist.
抗扭强度是金属抵抗被扭转的能力（性能）

力学性能的金属
力学性能的特点是反应的材料，适用于部队。这些属性分为五大类：强度，硬度，弹性，延展性和韧性。强度的能力抵抗金属适用于部队。强度性能通常被称为拉伸强度，弯曲强度，抗压强度，扭转强度，剪切强度和抗疲劳强度。拉伸强度是财产，抗拒力量撤出金属分开。这是一个最重要的因素在评价一个金属。抗压强度的能力是一种物质的抵抗被粉碎。压缩是相反的紧张局势方面的方向适用于负载。大多数金属具有较高的拉伸强度和抗压强度高。然而，脆性材料，如铸铁具有抗压强度高，但只是一个温和的拉伸强度。抗弯强度是质量抗拒部队成员造成弯曲或转移的方向，其中负荷应用实际上是一个弯曲应力是一个结合拉伸和压缩应力。扭强度的能力经受金属部队，造成一名成员的扭曲。
