Introduction This paper[2]has put forward a new project type“ steel bridge pavement + reinforcing fabric + shear connector + high toughness lightweight concrete + SMA-13”, as shown in Fig. 1 ,this project by welding shear connectoron a steel plate and colligating reinforcing fabric to improve the slip resistance ability and cooperative shape-shifting ability between toughness lightweight concrete and steel plate,eventuallyimproving the fatigue lifetime and its high and low temperature properties.
of light aggregate concrete (shear rivet) paving project.According to practical situation,contrastand analysis the influence factors such as shear rivet spacing, diameter, height and lightweight concrete pavement thickness.
Comprehensive consideration about the factors recommended shear rivet spacingof 400mm.
(3) Based on this analysis, through considering of construction technology, economic and other factors.
The influence of bridgetype, bridge span and bridge dynamic property also needs further exploration.

When examining the results obtained with empirical and model research, it has been shown that in the structural design of carbon fiber drive shafts, the main factor affecting the right development of the structure should be dynamic criterion, since the only use of static criteria leads to big errors.
The basic rheological properties are: elasticity, viscosity, plasticity.
Maxwell and Kelvin-Voigt models constitute the basic models of viscoelastic body and characterise its properties in a simplified and idealised way.
The most often it is assumed that elasticity is a non-linear function of deformation, while viscous properties depend on the deformation speed.

Several fundamental material properties can be estimated from the fracture surfaces of specimens failed during ultrasonic VHCF tests.
In the VHCF literature, the critical Stress Intensity Factor (SIF) is generally estimated by applying analytical SIF formulations to the typical semi-circular surface crack geometry revealed by fracture surfaces at final failure.
Introduction Critical Stress Intensity Factor (SIF) is one of the most important material properties to predict the onset of the unstable crack growth in cracked bodies.
Size effect thus affects critical SIF: the larger the size, the smaller the critical SIF.

As a polymer material, the PP packaging belt has rheological properties.
The rheological properties of polymer materials are closely related with the stress.
The corresponding shift factors are shown in Fig. 5.
The shift factors of PP packaging belt on the creep compliance curves are calculated by non-linear fitting.
Therefore, the shift factors of stress of this PP packaging belt can be get

Introduction Increasing global attention has been given to the reduction of dredged sludge volume before its disposal or reuse[1].The significant factor of sludge handling system is the dewatering operation.
More clay composition and higher water retention performance increase the difficulty of dehydration.Understanding the factors that influence sludge dewaterability is crucial for the effective improvement of sludge dewaterability[2].

These cracks result in a decrease in the mechanical performances and durability parameters of the material.
The mechanism of ISA is complex depending on various factors.
These factors have been classified into four groups, which are the thermal conditions at early-age, the cement-matrix composites, physical properties of the material (porosity, microcracking and strength, etc.) and the conservation environment.

The significance of the nano-particle surface modification is that people can have more freedom on the modification of nano-particle, not only the physical and chemical effects of nano-particle can be understood, but also the application of nano- particle can be extended; The purpose of nano-particle’ surface modification may be classified into four aspects ,that is improving or changing the dispersibility of nano-partical, increasing the surface activity of nano-partical, creating new effects of physics, chemistry, mechanical properties or new functions on the surface of nano-particals and improving the compatibility of the nano-particals with other materials[1-2] .
Coating the surface of nano-powder to change its properties is an important method of surface coated modification, and the shell material can be inorganic or organic.
The nano-partical with a coating of different chemical composition on its surface has remarkable peculiarities, such as biological compatibility, or good thermal, mechanical and chemical stability with special optical, magnetic, electrical, catalysis, hydrophilic, hydrophobic and sintering properties.
Precursor’s single factors analysis Coating mechanism shows that there are some factors influencing the modification quality, such as the choice of pH which is critical, and the concentration of AlCl3 as well as the mass ratio of nuclear and shell have impact on the coating rate and the thickness of shell material.
What’s more ,the choice of precursors’ pH value can directly affect the precursors’ filteration condition, the coated powders and the particle size.

The aspects analysed include the variation of initial out-of-plane imperfection and material properties.
The results show that among those considered the most relevant parameters affecting the buckling and post-buckling behaviour of uniaxially loaded plates are the level of initial imperfections present.
In order to assess the influence of material properties, Grade B and API X52 steels were modelled.
The elastic and plastic properties of the materials were defined by a Ramberg-Osgood model.
Table 1 summarises the steel properties as implemented in the finite element models.

Researchers have suggested stochastic and deterministic factors responsible for quality of laminate and pattern of flow.
Temperature of mold, infusion pressure and rate of flow are the deterministic factors [14].
In this work an attempt has been made to use a greater volume fraction of reinforcement as it contributes significantly to the mechanical properties.
Factors affecting mechanical properties of the laminate are curing, length, shape, orientation of fiber, viscosity of the resin, voids, wettability and permeability.
Conclusion It can be concluded that higher percentage of volume of fibers yields higher mechanical properties with fabric of 0.3mm thickness and 7781 fabric style of e-glass fibers.
