特殊測(cè)試項(xiàng)目:
1.彈性系數(shù)即彈性楊氏模量
定義:同相位的法向應(yīng)力分量與法向應(yīng)變之比。為測(cè)定材料剛性之系數(shù),其值越高,材料越強(qiáng)韌。
2.比例限:荷重在一定范圍內(nèi)與伸長(zhǎng)可以維持成正比之關(guān)系,其zui大應(yīng)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(yīng)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(diǎn):材料拉伸時(shí),變形增快而應(yīng)力不變,此點(diǎn)即為屈服點(diǎn)。屈服點(diǎn)分為上下屈服點(diǎn),一般以上屈服點(diǎn)作為屈服點(diǎn)。
屈服(yield):荷重超過(guò)比例限與伸長(zhǎng)不再成正比,荷重會(huì)突降,然后在一段時(shí)間內(nèi),上下起伏,伸長(zhǎng)發(fā)生較大變化,這種現(xiàn)象叫作屈服。
7.屈服強(qiáng)度:拉伸時(shí),*伸長(zhǎng)率達(dá)到某一規(guī)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(jī)上,以一定的速度將試樣拉伸到一定的伸長(zhǎng)率或拉伸到規(guī)定的負(fù)荷時(shí),測(cè)定試樣收縮時(shí)恢復(fù)的功和伸張時(shí)消耗的功之比的百分?jǐn)?shù),即為有效彈性;測(cè)定試樣伸長(zhǎng)、收縮時(shí)所損失的能與伸長(zhǎng)時(shí)所消耗的功之比的百分?jǐn)?shù),即為滯后損失。
