具有公共顶点的刚性三角块模式时最佳单位上限解的研究

Study on optimum unit upper limit solution when divided mode of rigid triangles has common vertex

推出一种用于计算金属塑性平面变形问题的上限公式 ,在此基础上利用

The paper derives an upper limit formula which can be used to solve metal plastic problems of plane deformation,on the basis of the formula,by means of Lagrange's method of multipliers studies the divided pattern when the unit upper limit solution is optimum.
