Heat is, or should be, involved in most every modeling application and example. Structural mechanics is not an exception. When heat is applied to a structural entity, deformation will occur due to the Thermal Stress applied to it. The Thermal Stress interface is included in COMSOL Multiphysics partially for this very reason. This video demonstrates the steps invovled and the results generated when adding a thermal stress to a bracket geometry before a load is ever applied to it. The steps shown here can be combined with the introductory bracket model. Watch the Structural Mechanics: Static Linear Analysis video to learn how to create the bracket model.
几乎所有建模应用和案例都会（或应该会）涉及热现象，结构力学也不例外。当热作用于结构实体时，实体会因为受到“热应力”而发生变形。正因为如此，COMSOL Multiphysics 提供“热应力”接口专用于此类分析。本视频演示在对支架几何施加载荷之前，在其中添加热应力的具体步骤以及产生的结果。您可以使用基础支架模型来练习这些步骤。欢迎观看“结构力学：静态线性分析”视频，学习如何创建支架模型。
