摘要
提出了在屈服平台范围内材料曲线的“对数幂函数表示法”以及它的相似准则,较普遍地认识了适合西曼斯基曲线[1]的材料性能,并列举了材料曲线相似准则在工程方面的一些应用。为论证本表示法的描述精度,本文提供了一批材料试验数据。
The logarithmic POwer function method and the similarity criterion expressing the material curves during the period of yield point elongation are provided in this paper, thus the performance of the materials fitting Simansky curve (1 ) is generallyunderstood. meanwhile some applications of the similarity criterion for material curves are listed. In order to describe the precision of the above method, some batches of material test data are shown here.
