提出了一种基于实验室原始数据的集中接触润滑剪切流变模型。该模型是一种修正了极限剪应力的Maxwell模型。材料需要三个特性：低剪切应力粘度、极限弹性剪切模数和材料所能承受的极限剪切应力。这三个都是温度和压力的函数。在将该模型应用于EHD接触时，预测的响应具有文献中报道的几个实验所期望的特征，并且在一个可以进行直接比较的特定情况下，显示出良好的数值一致性。
A shear rheological model based on primary laboratory data is proposed for concentrated contact lubrication. The model is a Maxwell model modified with a limiting shear stress. Three material properties are required: Low shear stress viscosity, limiting elastic shear modulus, and the limiting shear stress the material can withstand. All three are functions of temperature and pressure. In applying the model to EHD contacts the predicted response possesses the characteristics expected from several experiments reported in the literature and, in one specific case where direct comparison could be made, good numerical agreement is shown.
