应变梯度塑性理论,由于含有內禀材料长度,可以很好地描述尺寸效应,界面效应以及应变局部化现象等。为了建立內禀材料长度与位错微结构之间的关系,开展了不同位错源长度(100纳米,200纳米,300纳米)的三晶材料的三维离散位错动力学模拟。

Quantitative study of hydration degree of composite binder by image analysis and non-evaporable wate
The quantitative determination of reaction degrees of cement and mineral admixture in composite binder is important to understand its hydration mechanism and microstructure development.The reaction de
Modification of rapid chloride migration method based on the electrical conductivity of pore solutio
The chloride permeability of concrete is mainly depended on the transport properties of concrete, while the results of rapid chloride migration (RCM) methods, which is virtually measurement of electri
Concrete materials are ubiquitous in the developed world due to their versatility and cost-effectiveness as a construction material, but their great potential for increased functionality remains under
A review of alternative approaches to the reduction of CO2 emissions associated with the manufacture
In this review we discuss a wide range of alternative approaches to the reduction of CO2 emissions associated with the manufacture of the binder phase in concrete.They are classified broadly as follow
The durability of concrete has attracted significant attention over the past several decades and is still a research hotspot until now.This paper reviews and discusses recent research activities on th
The paper reviews the current status of service life prediction and performance testing for concrete structures.Part I emphasizes the advantages of performance-based approaches to durability predictio
Durability problems in concrete can often be linked to a high permeability, which is either caused by a high matrix permeability or the presence of cracks.Therefore, treatments that reduce the permeab
Mutual interaction between the hydration of Portland cement and the structure and stoichiometry of C
A mutual interaction occurs between the kinetics of the hydration of Portland cement and hydrated calcium silicate(C-S-H) formed as a result of the chemical reactions involved.The liquid phase composi
In cement chemistry, ferrite is one of the important liquid phases for producing industrial clinker.The reactivity of ferrite has not been investigated extensively and it is commonly assumed thatit hy
功能梯度压电材料(Functionally Graded piezoelectric materials,FGPMs)是一种材料弹性参数和电学参数沿某一方向连续变化的复合压电材料。其具有传统压电材料特性,能够实现机械能和电能间的相互转化的特性。由于传统压电材料为为了获得更大的位移和驱动力而采用的多层结构,往往会在不同层间界面处存在材料的失配,从而导致界面处开裂,蠕变和脱落,进而大大影响了器件的稳定
