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。
