There seems to be a basic misconception in several recent papers concerning the material symmetry of bodies in configurations that are pre-stressed. In this short paper we point to the source of the error and show that the material symmetry that is possible depends on the nature of the pre-stress. We also extend the results for material symmetry which have been well-known within the context of simple elastic solids to the general class of simple materials. This generalization has relevance to the material symmetry of biological solids that are viscoelastic.

残余应力和材料对称性

最近几篇关于预应力结构中物体的材料对称性的论文似乎存在一个基本的误解。在这篇简短的论文中，我们指出了误差的来源，并表明可能的材料对称性取决于预应力的性质。我们还将简单弹性固体中众所周知的材料对称性结果扩展到一般类型的简单材料。这种概括与粘弹性生物固体的材料对称性相关。
