1、將實驗或分析得到的數(shù)據(jù)整理在Excel中。
2、將數(shù)據(jù)寫成CAD中的輸入坐標(biāo)形式，即將兩列數(shù)據(jù)(力和位移)合并到一列并在中間加入逗號。其方法：假設(shè)將A，B列數(shù)據(jù)合并在C列，c1輸入 =a1&b1 ，回車確定。若在中間需加入逗號(,)，則為 =a1&","&b1 。
注意：將位移和力通過單位轉(zhuǎn)換，使二者在數(shù)量級上差不多，不然在CAD中畫出的圖可能尺寸相差太大而看不出呈環(huán)形，不易操作。
3、在CAD中畫出滯回環(huán)：在CAD中點擊多段線繪圖工具，將上面整合成的坐標(biāo)復(fù)制并粘貼到CAD中，便形成了滯回環(huán)。
注意：實驗數(shù)據(jù)可能因有毛刺等會在局部有多個重合、反復(fù)點，可刪除毛刺，并保證曲線閉合。
4、（1）形成面域：命令REG；（2）求面積：命令MASSPROP。
