摘要
材料力学是固体力学的一个分支,主要分析构件在外力作用下的受力、变形及破坏规律,为合理选择材料和设计构件形状提供有关强度、刚度与稳定性分析的基本理论与方法。构件在外力作用下发生弯曲是常见现象,结合构件材料相应的设计强度,通过材料力学弯曲正应力分析,才能保证构件不被破坏,结构才能够正常安全工作。论文以具体工程构件为例,结合公式对弯曲正应力计算原理在土木工程中的具体应用进行剖析,体现了材料力学弯曲正应力基本原理在土木工程建设中起到了不可替代的作用。
Material mechanics is a branch of solid mechanics. It mainly analyzes the force, deformation and failure law of the component under external force. It provides the basic theory and method for the analysis of strength, stiffness and stability for the rational selection of material and the shape of the design component. It is a common phenomenon that the component is bending under external force. Combining the corresponding design strength of the component material and the positive stress analysis of the mechanical bending of the material, can the component be avoided to be destroyed and the structure can work safely.
