在本文中，我们研究固体热弹性响应的状态方程，固体能够经历大的弹性变形。特别地，我们导出了各向同性物体在均匀温度下的均匀纯应变的应力-变形-温度关系。这些应用于类橡胶固体的热力学建模，特别参考单轴应力测试。讨论了橡胶中观察到的热弹性效应，并说明了如何通过选择合适的自由能函数来预测这些效应。
In this article we examine the equations of state for the thermoelaslic response of solids, which are capable of undergoing large elastic deformations. In particular, we derive the stress-deformation-temperature relations for the homogeneous pure strain of an isotropic body at uniform temperature. These are applied to the modeling of the thermomechanics of rubberlike solids with particular reference to the uniaxial stress test. Observed thermoelaslic effects in rubber are discussed, and it is shown how these can be predicted by selecting suitable forms of free-energy function.
