【摘要】 在分析了变形体和模具的接触特点和接触面金属的流动应力与应变特点的基础上,在考虑接触摩擦为最大剪应力K的情况下,绘制出接触面的滑移线场,应用滑移线理论求解出接触金属进入塑性区的极限载荷,并以此为标准来判断接触金属是否进入塑性区。更多还原

【Abstract】 Based on the analysis of the stress and strain of interface and contact characteristics of deformation body and die,and under the consideration of the maximum contact shearing stress K, this paper draws out the slipline field based on graphic solution of slipline theory and finds the solution of limit load of metal that plastic deformation initially take place. The limit load can be used as a criterion to the same problem.更多还原
