文献[1]发表后,我们写了《对〈铸铁单向压缩破坏的最大剪应力理论之否定〉一文的讨论》,于1985年11月投寄《力学与实践》.今又看到文献[2]和[3],想再谈几点看法.1.文献[1]是从宏观分析来否定最大剪应力理论的.虽然结论中有“被现有宏观理论所否定的最大拉应力”一句,但人们只是在文献[3]发表后才知道作者的结论是从细观得出的.鉴于文献[3]亦未给出这个问题的细观分析,所以这里仍限于从宏观来讨论问题.2.对于最大拉应变理论,文献[3]不再象文献[1]
After the publication of [1], we wrote “Discussions on the “Negative Seismic Theory of Uniaxial Compression Failure of Cast Iron” article, which was published in the “Mechanics and Practice” in November 1985. 2] and [3], I would like to talk about a few points. 1. The literature [1] is to deny the maximum shear stress theory from a macroscopic analysis. Although there is a sentence in the conclusion that “the maximum tensile stress is negated by existing macroscopic theories” However, only after the publication of the literature [3] did the author know that the author’s conclusion was derived from a detailed view. Since the literature [3] also did not give a detailed analysis of this issue, it is still limited to discussing the problem from the macroscopic point of view. 2. For the theory of maximum tensile strain, the literature [3] no longer resembles the literature [1]
