提出了多孔金属的塑性理论。根据不同表观密度的烧结铜的应力-应变曲线，利用基本方程计算无孔铜的应力-应变曲线。将方程应用于无摩擦闭模压缩，评估压缩方向上的应力与相对密度的关系，并与实验结果进行比较。
A plasticity theory for porous metals is proposed. From the stress-strain curves for sintered copper with various apparent densities, the stress-strain curves for pore-free copper is calculated by utilizing the basic equations.The equations are applied to frictionless closed-die compression and the stress in the direction of compression is evaluated in relation to the relative density and is compared with experimental results.
