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,材料的变形完全消失。
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。
