特殊測試項目：
1.彈性系數即彈性楊氏模量
定義：同相位的法向應力分量與法向應變之比。為測定材料剛性之系數，其值越高，材料越強韌。
2.比例限：荷重在一定范圍內與伸長可以維持成正比之關系，其zui大應力即為比極限。
3.彈性限：為材料所能承受而不呈*變形之zui大應力。
4.彈性變形：除去荷重后，材料的變形*消失。
5.*變形：除去荷重后，材料仍殘留變形。
6.屈服點：材料拉伸時，變形增快而應力不變，此點即為屈服點。屈服點分為上下屈服點，一般以上屈服點作為屈服點。
屈服（yield）：荷重超過比例限與伸長不再成正比，荷重會突降，然后在一段時間內，上下起伏，伸長發生較大變化，這種現象叫作屈服。
7.屈服強度：拉伸時，*伸長率達到某一規定值之荷重，除以平行部原斷面積，所得之商。
8.彈簧K值：與變形同相位的作用力分量與形變之比。
9.有效彈性和滯后損失：
在拉力機上，以一定的速度將試樣拉伸到一定的伸長率或拉伸到規定的負荷時，測定試樣收縮時恢復的功和伸張時消耗的功之比的百分數，即為有效彈性；測定試樣伸長、收縮時所損失的能與伸長時所消耗的功之比的百分數，即為滯后損失。
