摘要
借助数学工具解决弹性力学的基本问题,在弹性力学基本假定下详细解释什么是应力,其中包括应力的基本概念、如何描述一点处的应力状态及应力球张量与应力偏张量的基本内涵,并给出了定解问题所必须的边界条件,以及转轴作用下的应力转换方法和应力张量与应力偏量.
This thesis mainly explains what stress is according to the basic hypothesis of elasticity, which consists of the concept of stress, the description of the stress status at/around a certain point, along with the basic concept of hydrostatic stress tensor and deviatoric stress tensor. Meanwhile, it brings forth the necessary boundary conditions of definite solution and the stress transform methods in the effect of shaft.
