摘要
本文叙述了双金属管拉拔复合过程中的变形特点。在适当简化的前提下,建立了运动许可速度场,导出了拔制应力的上限解,并对稳定拔制条件和模角的选定进行了讨论。
The deformation of bi-metal tube has been described during the processing of material combinations. Using the upper bound theory, an analytical method has been newly developed, The condition of stable drawing and the determinaton of dicangle are discussed.
