以鉆頭使用時間與軸承壽命(小時)之比Z來確定。Z≤1/8為1級;1/8<Z≤2/8為2級;依此類推直至8級。
19、鉆頭直徑磨損bit gage wear:
直接以鉆頭直徑磨損的毫米數來表示。零表示直徑沒有減少,磨損量在兩個相鄰整數之間取數值大的整數。
20、鉆頭磨損特征dull bit appearance:
使用過的鉆頭與新鉆頭相比,在外觀上的明顯變化。
這種晶向條件下,熔池坐標系(x-y-z)與晶向坐標系重合。如果將基材繞x/[100]、y/[010]或z/[001]軸旋轉某個角度ξi(i=x, y, z),則可獲得其他晶向條件(見圖 11(a)[60])。

2.4 邊界條件和預應力施加
(1)邊界條件
柱端和梁端約束X、Y和Z方向的位移,模擬鉸接約束。
(2)預應力施加
預應力鋼筋中的預應力是通過降溫進行施加的。
2.5 加載制度
(1)柱頂軸壓
以0.3為軸壓比控制值,在柱頂施加恒定軸向荷載N。
