【摘要】 本文提出了金属材料的一种近似线性化初始屈服函数,它是位在Tresca六边形和双剪应力六边形之间的十二边形(族).应用这种屈服函数进行结构极限分析,计算工作量增加不多,可以得到精度比较好的结果.更多还原

【Abstract】 A set of approximate linearized yield-functions is presented for metal materials. It is a set of polygons with twelve edges which locates between the Tresca’s hexagon and the twin shear-stress-hexagon. Using this yield-function in the limit analysis of constructions, a more accurate solution can be obtained.更多还原
