摘要
本文讨论了材料力学中有关应力、应变分析的几个问题。给出简便直观的方法判定平面应力状态主应力的方向;利用二元函数求极大值的方法得出三向应力状态的最大正应力和最大剪应力;通过广义虎克定律导出平面应力状态下一点处三个方向的线应变与主应变的关系式。
This artical is about the topics on analysis of stress and strain in mechanics of materials.It provides a simple and direct way to decide the directions of principal stresses for plane stress states.The maximum normal stress and the maximum shearing stress are obtained by finding the maximum of a binary function.The relations between strains of any three directions and principal strains at a point for plane stress states are derived by,using Hooke’s law.
