宏观唯象本构模型被用来描述铁电弹性材料的行为。这种模型的一个代表性例子是兰迪斯提出的模型。近年来,作者将该模型应用于实际问题。在这种情况下,出现了几个问题,导致计算失败。本文件的目的是提请注意这些困难,并在可能的情况下提供解决战略。三个不同的问题进行了详细讨论。这些包括(1)不确定的线性模量的出现,(2)由于压电张量的函数形式的特定选择而出现的负开关乘数,以及(3)由于开关表面的函数形式的特定选择而出现的负开关乘数。此外,本文旨在作为进一步研究的动机。
Macroscopic phenomenological constitutive models are used in order to describe the behavior of ferroelectroelastic materials. A representative example for such a model is the one proposed by Landis. During recent years, the authors of the present paper applied this model for practical problems. In this context, several problems occurred, which lead to failure of the computations. The purpose of the paper is to draw attention to these difficulties and to provide solution strategies where possible. Three different issues are discussed in detail. These include (1) the occurrence of indefinite linear moduli, (2) the occurrence of negative switching multipliers due to the particular choice of the functional form for the tensor of piezoelectricity, and (3) the occurrence of negative switching multipliers due to the particular choice of the functional form for the switching surface. Moreover, the paper is intended to serve as a motivation for further research.
