This commentary on thermodynamics in solid mechanics aims to provide an overview of the main concepts of thermodynamic processes as they apply to, and may be exploited for, studies in nonlinear solid mechanics. We give a descriptive commentary on the (physical) interpretation of these concepts, and relate these where appropriate to behaviour of solids under thermo-mechanical conditions. The motivation is firstly that students of solid mechanics have often had less exposure to thermodynamics than those in other branches of science and engineering, yet there is great value in analytical formulations of material behaviour derived from the principles of thermodynamics. It also sets the contributions in this Theme Issue in context. Along with the deliberately descriptive treatment of thermodynamics, we do outline the main mathematical statements that define the subject, knowing that full details are provided by the authors in their corresponding contributions to this issue. The commentary ends on a lighter note. In order to aid understanding and to stimulate discussion of thermodynamics in solid mechanics, we have invented a number of very basic and completely fictitious materials. These have strange and extreme behaviours that describe certain thermodynamics concepts, such as entropy, in isolation from the complexities of real material behaviour.
这篇关于固体力学中热力学的评论旨在概述热力学过程的主要概念，这些概念适用于非线性固体力学研究，并可用于该领域的研究。我们对这些概念的（物理）解释进行了描述性评论，并在适当的地方将其与固体在热机械条件下的行为联系起来。这样做的动机首先是，固体力学专业的学生接触热力学的机会通常比其他科学和工程领域的学生少，然而，从热力学原理推导出来的材料行为分析公式具有很大的价值。这也为本期专题中的论文提供了背景。除了对热力学进行特意的描述性阐述外，我们还概述了定义该学科的主要数学表述，因为我们知道作者在他们为本刊撰写的相应论文中提供了完整的细节。评论以轻松的方式结束。为了帮助理解并激发对固体力学中热力学的讨论，我们虚构了一些非常基础且完全虚构的材料。这些材料具有奇特和极端的行为，能孤立地描述某些热力学概念，如熵，而不涉及实际材料行为的复杂性。
