The curve of dynamic modulus versus the conductive filler volume percent showed that the dynamic modulus of the composites changed with increase of the filler volume percent and exhibited a transition phenomenon . it is believed that these results mentioned above were related to the filler dispersion and the interaction between filler and polymer 通过研究动态流变行为对导电填料含量的依赖性,发现导电填料含量增浙江大学硕士学位论文加,体系的动态模量存在一转变现象,被认为与颗粒在聚合物中的分散、填料与聚合物间相互作用密切相关。
The lead zirconate titanate ( pzt ) / polymer composite presented large tan5 and dynamic modulus when the composites were exposed to higher polarization voltage and longer polarization time , because of the uniform dispersion of ceramic in polymer matrix and the strong interaction between grain and polymer . the morphology of the composites , namely the degree of the grains dispersion in polymer , can be observed through scanning electric microscope ( sem ) 颗粒结构性高的压电陶瓷,其复合体系内耗大;在高极化电压、长极化时间下,压电陶瓷颗粒在聚合物中分散比较均匀,与聚合物接触面大,相互间作用强;在外力作用时,体系tanb 、 g , , g ?呈现大的值。
The job of this paper was divided into two parts mainly . firstly , the numerical simulation approach for polygonal aggregate was presented . secondly , the space analysis model for dynamic modulus of elasticity of concrete was set up , and a series of theories analysis and calculations to the model were performed 本文的工作主要分为两部分,首先提出了混凝土多边形骨料的数值模拟方法,然后为了研究混凝土的动态弹性模量建立了空间分析模型,并对模型进行了一系列理论分析和计算。
Dynamic modulus is the ratio of stress to strain under vibratory conditions (calculated from data obtained from either free or forced vibration tests, in shear, compression, or elongation). It is a property of viscoelastic materials.
