人们将填充橡胶的动态模量随着应变的增加而急剧下降的现象称为Panye效应。
佩恩的效果是橡胶的应力-应变行为的特定特性,尤其是橡胶化合物含有炭黑等填料。它是英国橡胶科学家命名的a·r·佩恩广泛研究的效果(例如佩恩1962)。有时也称为Fletcher-Gent效应的影响,经过作者的第一个研究的现象(弗莱彻和绅士1953)。效果观察与应变振幅小,在循环加载条件下,表现为粘弹性储能模量的依赖应用应变的振幅。大约0.1%以上应变振幅,存储模量随振幅的增加而迅速减小。在足够大的应变振幅(约20%),存储模量方法一个下界。在这一地区的储能模量降低了损耗模量最大。佩恩的效果取决于材料的填充内容和未交货弹性体消失。身体上,佩恩效应可以归因于deformation-inced材料微观结构的变化,即破碎和复苏疲弱的身体债券连接相邻填料集群。自佩恩效应是至关重要的频率和amplitude-dependent动态刚度和阻尼行为橡胶衬套、汽车轮胎等产品,本构模型来表示它已经发展在过去(例如狮子et al . 2003年)。类似于小变形下的佩恩效应是大变形下的马林斯效果观察——实在不懂，这是有道翻译，以下是原文
The Payne effect is a particular feature of the stress-strain behaviour of rubber, especially rubber compounds containing fillers such as carbon black. It is named after the British rubber scientist A. R. Payne, who made extensive studies of the effect (e.g. Payne 1962). The effect is sometimes also known as the Fletcher-Gent effect, after the authors of the first study of the phenomenon (Fletcher & Gent 1953). The effect is observed under cyclic loading conditions with small strain amplitudes, and is manifest as a dependence of the viscoelastic storage molus on the amplitude of the applied strain. Above approximately 0.1% strain amplitude, the storage molus decreases rapidly with increasing amplitude. At sufficiently large strain amplitudes (roughly 20%), the storage molus approaches a lower bound. In that region where the storage molus decreases the loss molus shows a maximum. The Payne effect depends on the filler content of the material and vanishes for unfilled elastomers. Physically, the Payne effect can be attributed to deformation-inced changes in the material's microstructure, i.e. to breakage and recovery of weak physical bonds linking adjacent filler clusters. Since the Payne effect is essential for the frequency and amplitude-dependent dynamic stiffness and damping behaviour of rubber bushings, automotive tyres and other procts, constitutive models to represent it have been developed in the past (e.g. Lion et al. 2003). Similar to the Payne effect under small deformations is the Mullins effect that is observed under large deformations

对于Pyane效应,Pyane本人的解释是:动态模量的下降是由于填料间的物理作用力的破坏,而能量耗散的增加则是由于聚集体的不断的破坏重组造成的。

动态弹性模量对应变的依赖性是佩恩效应
