摘要
可压缩烧结材料变形时体积发生变化,塑性理论只能建立在质量不变条件之上,金属塑性力学理论范畴的初等解析法、滑移线法、有限元法以及上限分析法为求解不同状况下的可压缩烧结材料塑性变形问题提供了有效的途径。
The theory of plasticity is only based on mass constancy condition because volume of deformation body is changed with plastic deformation for compressible sintering materials.The elementary analytical method and slip line method and FEM and upper bound method are useful ways for solving questions of different plastic deformation process on the metal plastic mechanics of compressible sintering materials.
