论文摘要
本文模拟了在弹性体的循环载荷和卸载过程中的压力软化。该论文首先要重塑初级加载曲线以包括软化功能，并继续推导非线性横向各向同性本构方程，以进行弹性响应，应力松弛，残留应变和残留应变的蠕变。这些想法与Arruda-Boyce八链模型的横向各向同性版本结合在一起，以开发一种本构之间的关系，该关系能够在跨性别各向同性，超弹性材料（尤其是富含碳填充的橡胶橡胶材料）中准确地表示循环压力期间的Mullins效应。关键词：穆林斯效应，压力较高，滞后，应力松弛，残留应变，残留应变的蠕变，横向各向同性。 MSC代码：74B20，74D10，74L15
This paper models stress softening during cyclic loading and unloading of an elastomer. The paper begins by remodelling the primary loading curve to include a softening function and goes on to derive non-linear transversely isotropic constitutive equations for the elastic response, stress relaxation, residual strain and creep of residual strain. These ideas are combined with a transversely isotropic version of the Arruda-Boyce eight-chain model to develop a constitutive relation that is capable of accurately representing the Mullins effect during cyclic stress-softening for a transversely isotropic, hyperelastic material, in particular a carbon-filled rubber vulcanizate. Keywords: Mullins effect, stress-softening, hysteresis, stress relaxation, residual strain, creep of residual strain, transverse isotropy. MSC codes: 74B20, 74D10, 74L15
