Differences between the two beam designs (single vs. multiple web openings) can be significant in terms of distance between openings and structural performance due to other related factors.
The investigation of the said structural characteristics involved enlarging the web opening area ratio in the multi web openings and the steel tube’s width-thickness ratio (H/t), and using the web openings’ area ratio and location and the type of fiber that affect the structural performance as the main variables.
Mechanical properties of material To identify the properties of materials used in the manufacture of HPRWO, tensile strength testing was performed on the steel, and compressive strength testing on the concrete.

Moreover, the new polymer materials also have excellent optical, electrochemical and microwave absorption properties.
However, due to the poor comprehensive mechanical properties, insolubility in common organic solvents and poor rheological properties, it is difficult to process PANI with conventional molding methods and the large-scale applications of PANI in various fields are seriously hindered [9].
The electrical conductivity improvement also greatly enhances the electrochemical properties of the materials.
For COMPASS field is an ab initio parameterized force field, the relevant properties of condensed phrase can be effectively obtained.
In the COMPASS force field, since the hydrogen bond is recessive and can not be included in the calculation, the primary consideration factors include Van der Waals force and Coulomb force.

The resultant MMC samples were characterized to determine their thermal, electrical and mechanical properties in respect to varying particle sizes (212, 425, 710 and 1200 mm) of the SiC.
These properties were achieved for a 60%Cu/Al(40%SiC) at 212 µm, 50%Cu/Al(50%SiC at 12 µm and 70%Cu/Al(30%SiC) at 710 µm.
Copper and aluminum based materials are of high interest in these applications due to their properties, availability and relatively low cost.
In recent years, a great interest is being directed to the metal-matrix composites (MMCs) due to their superior mechanical, thermal and electrical properties, weight saving, increased component life, and improved recyclability [1 – 2].
The thermo- electrical properties will be discussed as a function of the reinforcement.

Introduction Ni30 superalloy is a new solution-strengthened nickel-based superalloy, which has good high temperature strength, high temperature oxidation resistance, gas corrosion resistance and mechanical properties.
At present, the influence of solution aging treatment on the microstructure and mechanical properties of nickel-based superalloys at home and abroad mainly focuses on the best solution aging treatment process, recrystallization, grain growth behavior, precipitation and dissolution of strengthened phase, and the effect of aging treatment system [4,5] on alloy properties.

However, the studies mentioned above have been made to study the effect of some parameters that affect the life of the die.
Factors to be considered in this work are material grain flow and forging force and tool stresses, which were then used to determine part quality and tool life.
Material properties, used in the FE simulation, for die insert and die ring shown in Table 1 were taken from reference [14].
The shear friction factor used in the analysis of each step is 0.1.

The natural characteristic of the negligible friction is a favorable factor but this result in a system with low damping performance.
Furthermore, to ensure high lateral mechanical stiffness, the air pressure is typically kept at a high value which causes the system to be susceptible to noise.
Thus, by varying the current, id, it is theoretically possible to alter the damping characteristics without affecting the other performance characteristics of the system.
An active eddy current damper is able to complement the damping without affecting the responsiveness of such a precision stage.

The studied fabric properties are the thermal behaviour, the air and water vapour permeabilities and drape.
This study comprises correlations among the above fabric properties and the search of fabric structural characteristics that negatively affect comfort.
For the first two situations, there is the contribution of mechanical and aesthetical properties, while, to warrant well being there are the called “comfort properties” that influence the behaviour of fabrics.
Explanation equations for comfort properties.
With these equations and manipulating the most relevant variables that explain the corresponding comfort properties (table 2.) optimisation of fabric comfort properties as a function of its use can be done.
