situation-display tube

The deforming situation of seamless steel tube in the tension reducing process was simulated by means of a large-scale and common finite-element analysis software ANSYS/ LS-DYNA, this simulation could present the deforming situation objectively.

采用ANSYS/LS-DYNA大型通用有限元分析软件对无缝钢管张力定径过程的金属变形行为进行了模拟，较直观适时地反映了该过程的金属变形状态。
