术语表
GLOSSARY OF TERMS
 
展延性
Ductility:
 

  变成永久性变形的能力 - 扩展,拉伸,或锤锻后在可预估的持续负载下不出现故障的能力。
  The ability of a material to become permanently deformed—stretched, drawn, or hammered without failure while maintaining an appreciable load.

     
抗拉强度
Tensile Strength:
 

  在出现问题前材料单位面积所能承受的极限拉力,例如:磅每平方英寸(PSI)。
  Measures in force per unit area [i.e. pounds per square inch (PSI)] the ultimate stress that can be withstood by a material in tension prior to failure.

     
屈服强度
Yield Strength:
 

  在出现永久性变形(塑性变形)前单位面积所承受的最大压力。
  Measures in force per unit area, the stress at which a material will undergo a permanent change in shape (plastic deformation) in response to an applied force.

     
伸张度
Elongation:
    施加拉力后材料出现塑性变形的百分比。
  Measures by percentage, the amount of plastic deformation a material will exhibit in response to a force applied in tension.
