特殊测试项目：
1.弹性系数即弹性杨氏模量
定义：同相位的法向应力分量与法向应变之比。为测定材料刚性之系数，其值越高，材料越强韧。
2.比例限：荷重在一定范围内与伸长可以维持成正比之关系，其zui大应力即为比极限。
3.弹性限：为材料所能承受而不呈*变形之zui大应力。
4.弹性变形：除去荷重后，材料的变形*消失。
5.*变形：除去荷重后，材料仍残留变形。
6.屈服点：材料拉伸时，变形增快而应力不变，此点即为屈服点。屈服点分为上下屈服点，一般以上屈服点作为屈服点。
屈服（yield）：荷重超过比例限与伸长不再成正比，荷重会突降，然后在一段时间内，上下起伏，伸长发生较大变化，这种现象叫作屈服。
7.屈服强度：拉伸时，*伸长率达到某一规定值之荷重，除以平行部原断面积，所得之商。
8.弹簧K值：与变形同相位的作用力分量与形变之比。
9.有效弹性和滞后损失：
在拉力机上，以一定的速度将试样拉伸到一定的伸长率或拉伸到规定的负荷时，测定试样收缩时恢复的功和伸张时消耗的功之比的百分数，即为有效弹性；测定试样伸长、收缩时所损失的能与伸长时所消耗的功之比的百分数，即为滞后损失。
