提出了有限粘弹性的三维本构模型。它考虑了振幅的依赖性，并且基于具有本征时间尺度的麦克斯韦链。这种类型的粘弹性在热力学上是一致的，并为模拟其他影响(例如，温度相关性)提供了基础。该模型的参数辨识在频域和时间域都是可能的。文中给出了一些有限元实现和在时间域中的仿真结果。只有在时间域中才有可能对多频和其他更复杂的加载过程进行数值模拟。一个非常有趣的加载过程是一个变化幅度的循环变形，以模拟佩恩效应的瞬时动态行为。(2019Wiley-VCH Verlag GmbH&Co.KGaA，Weinheim)
A threedimensional constitutive model of finite viscoelasticity will be presented. It considers the amplitude dependence and is based on a Maxwell chain with intrinsic time scales. This type of viscoelasticity is thermodynamically consistent and provides a basis for modelling other effects (e.g. temperature dependence). The parameter identification for this model is possible in both the frequency and the time domain. Some finite element implementation and simulation results in the time domain are presented. The numerical simulation of multifrequent and other more complicated loading processes is possible only in the time domain. A very interesting loading process is a cyclic deformation with changing amplitudes in order to simulate the transient dynamic behavior of the Payne‐effect. (© 2009 Wiley‐VCH Verlag GmbH & Co.
