摘要:
|
本文利用连续速度场解析了棒材辊拔与辊挤问题并获得上界解析解。该解与以主应力法得到的解析解进行比较表明,上界解略高于主应力法解析解。

A continuous velocity field is established and applied to the bar due to draw-out/extrusion by idle rolls, with an upper-bound analytical solution thus obtained. Compared with that using slab method, the solution can give little higher values than that of slab method.
