非线性弹性理论框架中的一个经典问题是在没有体积力的情况下可以维持反平面剪切的纯状态的材料的表征。70年代,诺尔斯和希尔在各向同性和不可压缩弹性的框架内解决了这个问题。在这里,我们提供了一个更简单和更短的证明这些经典的结果。此外,我们将这些结果推广到非线性弹性动力学,我们提供了一些新的特殊的解决方案。
A classical problem in the framework of nonlinear elasticity theory is the characterization of the materials that may sustain a pure state of anti-plane shear in the absence of body forces. This problem has been solved by Knowles and by Hill in the framework of isotropic and incompressible elasticity in the seventies. Here we provide a simpler and shorter proof of these classical results. Moreover, we extend these results to nonlinear elastodynamics and we provide some new special solutions.
