摘要
单相塑性材料的强度和塑性基本上是分别研究讨论的。此文以低碳深冲钢板为例,从能量观点出发,讨论了强度和塑性的内在制约关系,唯象地提出了单相塑性材料塑性破坏的判据,并解释了几个实验现象。此文的研究有助于加深对深冲钢塑性变形形为的理解。
In most papers , the strength and plasticity of single - hsed metals are discussed separately. In this paper, taking the deep-drawing sheet metals as an example,in the viewpoint of distortion energy, special attention has been given to the internal relationship of stength and plasticity . Phenomenally, criterion for Plastic destruction of plastic metal has been put forward. Some experimental results were explained in the lighe of the theory, the research in this paper heips understand deformstion process.
