项目摘要
For the purpose of clarification of relation between morphology, molecular dynamics and rheological properties, we developed the simulation program to predict the rheological properties by the molecular dynamics method using the Bead-Spring model and Tube model. The simulation results qualitatively presented the shear-rate dependence on the first normal stress difference and shear viscosity, which was seen for the actual polymer melts.We formulated the simulation model of deformation and breakup or a single droplet using only the physical properties or a droplet and a matrix liquid. It achieved success to represent the breakup of a droplet by the simulation, which has been impossible by means or the method or continuum mechanics. We performed the simulation for Newtonian-Newtonian system in the simple shearing flow field and its results were compared with the experimental observation. The simulation results showed the mode or breakup and the dependence or phisical properties on it, see … More n in the experiment. But the time-course of deformation and breakup in the simulation was not in agreement with experimental one.In the view point or macroscopic treatment, we developed the computer program of optimum determination of model parameters for the viscoelastic constitutive equations which could relatively well predict the behavior or polymer liquids, and studied the prediction accuracy or each model. Using these constitutive models, we carried out the viscoelastic flow analyses for the extrudate swell from the various shaped dies and film casting process. The several new informations on flow mechanism could be obtained, for example, requirement or consideration of irreversibility in reversed deformation for the extrudate swell problem, importance of ratio or extension-thickening nature in the uni-axial elongation to that in the planar elongation, etc. Also, three-dimensional analysis program or viscoelastic flow including the free surface was developed and the extrudate swell from the square channel in the low shear rate region was analyzed.

为了阐明形态学、分子动力学与流变学性质之间的关系,我们采用Bead-Spring模型和Tube模型开发了分子动力学方法预测流变学性质的模拟程序。模拟结果定性地给出了剪切速率对第一法向应力差和剪切粘度的依赖关系,这是在实际聚合物熔体中可以看到的。我们仅利用液滴和基质液体的物理性质,建立了单个液滴变形和破碎的模拟模型。成功地模拟了液滴的破碎过程,这是用连续介质力学的方法所不能实现的。对简单剪切流场中的牛顿-牛顿体系进行了数值模拟,并与实验结果进行了比较。模拟结果显示了模式或分裂以及对它的依赖性或物理性质,见 ...更多信息 n在实验中但模拟中的变形和破裂的时间过程与实验结果不一致,本文从宏观处理的角度出发,编制了能较好地预测聚合物液体行为的粘弹性本构方程模型参数优化确定的计算机程序,并对各模型的预测精度进行了研究。利用这些本构模型,我们进行了粘弹性流动分析的挤出物膨胀从各种形状的模具和薄膜流延过程。通过对挤出胀大问题的研究,得到了关于流动机理的一些新的信息,如对挤出胀大问题的反向变形不可逆性的要求或考虑,单向拉伸与平面拉伸的比例或拉伸增稠性质的重要性等。三开发了包含自由表面的粘弹性流动的量纲分析程序,并对挤出物在低剪切下从方形通道中溶胀的情况进行了分析率区域进行了分析。少
