Moreover , the dynamic rheological behaviors for conductive filler / piezoelectric ceramic / polymer composites have been studied . the results revealed that different conductive filler affected the dynamic modulus of the composite 导电填料/压电陶瓷/聚合物复合体系的动态流变行为研究结果表明,导电填料的种类影响复合体系流变行为。
The result shows that the dynamic modulus of sandy pebble soil reduces nonlinearly with the accretion of dynamic strain , but increases with consolidation ratio , and affected little by the vibration frequency 试验结果表明,砂卵石土呈现出动弹性模量随动应变的增大而非线性地降低,动荷载频率对动弹性模量影响很小,动弹性模量随着固结比的增大而显著增大的规律。
In this paper , some aspects such as the behavior of pore pressure of unsaturated loess , the dynamic constitutive relationship and the characteristics of the dynamic modulus , dynamic strength and dynamic damping ratio are studied with the dynamic torsional shear test of loess 在以上研究的基础上,本文又通过黄土的动扭剪试验研究了非饱和黄土的孔隙压力特性、动本构关系、动剪切模量特性、动强度特性以及动阻尼比特性。
This means the saturation degree of concrete is different . by means of analyzing the l9 ( 34 ) orthogonal table , the air content is the chief factor , the second factor is water binder ratio and the third is mineral admixture in both high water pressure and low water pressure . the water saturation degree of concrete in damaging point ( e6 / e0 = 60 % ) can be found by measuring the dynamic modulus of elasticity after six freezing - thawing cycles 采用l9 ( 34 )正交表对水胶比、含气量和掺合料三个因素进行分析,试验结果表明:在自然情况下,影响混凝土水饱和系数的主要因素是水胶比,而影响混凝土在盐溶液中饱和系数的主要因素则是含气量;在水压力作用下,无论压力大小,混凝土水饱和系数的影响次序依次为含气量、水胶比、掺合料。
After contrasting and analyzing the main design parameters " test methods of laboratory and field outside , it sets up the correlativities between the field bearing plate modulus and other parameters such as design dynamic modulus , benkleman bean static deflection , field cbr value , consistency and density . by means of laboratory experiment , it assays the influence of the consistency on laboratory bearing plate modulus and laboratory cbr values , and establishes the relationships between laboratory and field values . combined with the project , a more logical sub - grade quality test standard is put forward 通过对路基现场检测不同方法的对比分析,建立了设计动模量、贝克曼梁静弯沉、现场cbr 、稠度和压实度与现场承载板模量的关系;通过室内试验,分析了稠度对室内承载板、室内cbr的影响,并建立了室内外模量间的关系;在此基础上,结合工程实际,对不同检测方法进行了评价,提出了较为合理的路基施工质量检测标准。
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.
