稳态塑性变形问题的上限解法

Analysis of Steady State Plastic Deformation with Upper-bound Approach

提出了用上限法分析稳态塑性变形问题的一般方法，用双流超几何函数法导出了通用的运行许可速度场的数学表达式，并对平辊轧制问题进行了讨论，

general metheod of solving steaty state plastic deformation through upper-bound approchis presented on the basis of a general expression of Kinematically admissible velocity fields which is derivedby the doualstream function. Deformation during flat rolling is dissussed.
