本文使用有限元素軟體MARC，分析非對稱壓延加工中之同徑異周速、異徑同周速及異徑異周速，於乾摩擦條件下，曲率、壓延扭矩、壓延負荷之變化情形。在異徑壓延條件下輥徑的比值，板材與滾輪接觸所形成之入射角的容許變動範圍，及該入射角角度對成形板材曲率、壓延扭矩、與負荷的效應亦為本文所探討。以及壓下率和板材初始喂給速度的關係。
由本文得知，壓下率與推桿速度成反比。對於同徑異周速壓延，板材彎曲方向往周速慢之輥輪方向彎曲，且推桿速度與曲率值成正比。對於異徑同周速壓延板材彎曲方向往輥徑小之輥輪方向彎曲，且不同的推桿速度將造成曲率變化臨界點的改變，而入射角的變化則與曲率計值反比。對於異徑異周速壓延板材彎曲方向往切線速度較低的輥輪方向彎曲。
