摘要翻译:
我们研究了一个简单的理论模型的非线性流变学,该模型旨在模拟层状体系,如剪切作用下的层状结构。在本工作中,我们研究了该模型的一个二维版本,它在临界温度Tc下表现出平衡态的Kosterlitz-Thouless转变。体系在高温T>Tc时表现为牛顿流体,而在低温T<Tc时表现为剪切变稀。本模型中的非线性流变现象是由于边缘位错的运动而产生的,类似于超导体中涡旋运动的非线性输运现象。

英文摘要:
We study non-linear rheology of a simple theoretical model developed to mimic layered systems such as lamellar structures under shear. In the present work we study a 2-dimensional version of the model which exhibits a Kosterlitz-Thouless transition in equilibrium at a critical temperature Tc. While the system behaves as Newtonain fluid at high temperatures T > Tc, it exhibits shear thinning at low temperatures T < Tc. The non-linear rheology in the present model is understood as due to motions of edge dislocations and resembles the non-linear transport phenomena in superconductors by vortex motions.
