These basic parameters can be used to describe the linear and non-linear visco-elastic properties and even the destruction properties usually.
Thus, larger range of information of asphalt mixture can be analyzed without time and equipment constraints.As typical visco-elastic material, the properties of asphalt mixture are affected by many factors (such as temperature, frequency, time and load) and can not be derived easily.
Through nonlinear least squares fitting and time-temperature principle, the master curve and the factors were derived.
At 50℃, both shift factors were identical.

In this article, based on a high-speed Instron servo-controlled hydraulic materials test machine is adopted to investigate the strain rate-dependent properties of bending tensile properties for SFRC.
Introduction Extensive experimental research has been done on rate-dependent properties normal concrete [1,2, 5, 6, 8], but very little on the tensile properties of steel fiber reinforced concrete (SFRC)[9].
The mechanical properties of SFRC are determined by a number of factors including the elastic modulus and strengths of constituents; the aspect ratio, volume fraction, orientation and distribution of steel fibers; and the nature of the interface of steel fiber/matrix bond.
Meanwhile, the beam bending performance is affected by many factors, such as loading, span ratio, the orientation of the specimen, loading speed and the beam sizes, and so on.

In addition to these factors, the accurate measurements of the flow are the cornerstone in almost all industrial applications, such as oil/gas processing, food industry, and petrochemical and pharmaceutical plants.
The present study aims to investigate the effects of the Reynolds numbers and aspect ratios of a pipe conveying fluid including an orifice plate on the flow characteristics, and on the pipe mechanical properties.
The maximum effect of the mechanical properties of stress (a), strain (b), and the total deformation (c) are shown in Fig. 4, measured at Re number of 5000, 10000, and 15000 crossed by aspect ratio of 0.2,0.3, and 0.5.
However, at aspect ratio of 0.3, the trend of the mechanical properties appears to be significantly different.
The results concluded that somewhere between aspect ratio of 0.2 and 0.5, the mechanical properties have minimum values, which is an abnormal behavior.

Effects of Suspending Abrasives on the Lubrication Properties of Slurry in Chemical Mechanical Polishing of Silicon Wafer J.Y.
The lubrication properties of the slurry between the silicon wafer and the pad in chemical mechanical polishing (CMP) are critical to the planarity of the silicon wafer.
Moreover, the suspending abrasives, which are contained in the slurry, have an extremely important influence on the lubrication properties of the slurry.
The pitch angle has an important influence on the lubrication properties of the slurry in CMP.
