橡胶化合物表现出复杂的材料行为。率无关和率相关的非弹性性能进行了观察。这些特征可以通过粘弹性和弹塑性来建模，如文献中所指出的。由于轮胎在使用中是一个滚动结构，因此在仿真方法中考虑这种情况是非常重要的。因此，本文提出了新的和有效的配方稳态轧制结合粘弹性和弹塑性材料模型。具体的本构特征的基础上，作者在文献中提出的广义材料配方。本程序的基本思想是采用物质历史，这是一个时间的函数，作为空间分布在一个环的物质点的函数。为了避免非常耗时的计算，利用非局部材料方法的近似。这样，沿材料点环的沿着耦合项被抑制，并且获得非常有效的算法。该模型的背景下，稳态滚动结构，如一个简单的橡胶圈和复杂的轮胎模型。有关覆盖摘要，请参见ITRD E125059。
Rubber compounds exhibit complex material behavior. Rate-independent and rate-dependent inelastic properties are observed. These features can be modeled by viscoelasticity and elasto-plasticity as pointed out in the literature. As the tire in service is a rolling structure, it is of great importance to cover this situation in simulation approaches. Therefore, new and efficient formulations for steady-state rolling combined with viscoelastic and elastoplastic material models are presented in this paper. The specific constitutive characterizations are developed on the basis of generalized material formulations presented earlier in the literature by the author. The underlying idea of the present procedures is to employ the material history, which is a function of time, as a function of space distributed over a ring of material points. In order to avoid very time consuming computations, approximations of the non-local material approaches are utilized. This way coupling terms along the ring of material points are suppressed and very efficient algorithms obtained. The models are presented in the context of steady-state rolling structures like a simple rubber ring and complex tire models. For the covering abstract see ITRD E125059.
