| 摘 要： | 对应力分析设计法中的一些概念和有争议的问题进行了讨论。在介绍了各种类型应力特点的基础上，强调了应力分解与应力分类的不同，概括了应力分解和分类的正确方法。指出应力分解仅涉及如何将应力分解成均布应力，等效的线性分布应力和非线性应力分量，至于怎样将分解出的应力进行分类，完全是由应力所在位置和产生应力的外因决定的。同时也对峰值应力的分布类型、有无自限性和应力分解及分类中需要注意的问题给出了作者的观点。

| Abstract: | Some interesting issues in Design By Analysis(DBA) method are discussed.After a brief discussion of the features of primary,secondary and peak stresses,the emphasis is put on the difference between stress decomposition and stress clarification,and some appropriate measures in carrying out the DBA.In addition,other issues,like characteristics and self-limiting of peak stress are also discussed. |
