Combining with three nodes isoparametric axial force element, the new element can be used to accurately calculate the shear flow action between bar and skin in thin-wall structure.
它与三节点等参轴力杆单元组合时可以精确地模拟薄壁结构中杆与蒙皮之间的剪流作用。
CFD simulation results show that the entrance velocity is about 24% higher than the local flow velocity, resulting into large surface shear force, is consistent with the experimental results.
CFD模拟结果表明，直管试样入口处局部流速比平均流速高约24%，表面剪切力大，与实验结果一致。
A solid, however, no matter how plastic it is, dose not flow unless the net shear force on it exceeds a certain value.
但是，对于一种固体，无论其塑性如何，除非所受剪切力超过了某一限值，否则不会流动。
