Moreover, surfaces in many real-world applications are not “nominally” flat but instead exhibit an infinite variety of geometries with macroscopic curvature and roughness characteristics affecting interfacial phenomena, such as wettability [12].
Here, we develop a finite element (FE) model to examine the impact of nonlinearities arising from geometric factors, material rheology, and contact and friction characteristics.
Both frictionless and friction contact conditions are considered in the simulation in order to capture the role of interfacial shear stresses in affecting the contact behavior.

On this basis, the performance of the device is investigated, and the experimental research on the viscoelastic property of sponge material is carried out using the device.
Introduction In daily life femoral fracture caused by accidental falls is one of the important issues affecting the health of the elderly.
In the development of hip protector, sponge material is usually used to play buffer role, and the viscosity coefficient and elastic coefficient of sponge material are the key factors to absorb energy and to cushion impact.
When the mass m is given a displacement x on the equilibrium position in downward direction, there will produce a force on the mass, the mechanical model is shown in Fig. 1 (b).
However, the viscidity coefficient of sponge is related to the many factors such as density, hardness, composition and structure of the material, so hardness is only an influence factor.

The effects of rice straws/coir fibers (R/C) mass ratios on the physical (thickness swelling) and mechanical (modulus of rupture, modulus of elasticity and internal bond strength) properties of particleboard composites were investigated.

Introductions Mixing machine is machinery which using mechanical force and gravity e.g. and uniform mixing up two or more materials.
The characteristics of the flow field in internal mixer is the most basic evaluation to a new type of mixing equipment properties [1], from numerical simulation point of view, simulating mixing machine facing challenge is that the flow area surrounded by the liquid level, the trough wall, the stirring paddle and stirring shaft changes with time.

Introduction TiAlBN coating has gained much attention due to its superior properties in comparison to the most studied hard coating, such as the TiN, TiAlN, and TiBN.
In order to acquire desirable properties from the TiAlBN coating, the design of the coating’s microstructure is of particularly important.
One of the factors affecting the chemical composition of the n-TiAlBN coating is the nitrogen activity in the chamber.

Reaming is a common machining process with the characteristic properties of enlarging, smoothing and accurately producing the original holes to tight tolerances.
Some earlier researchers [7] argued that the hardness and thermal conductivity are considered as the material properties mainly responsible of the crater wear.
The analysis of variance (ANOVA) was performed for the factors and their contribution rates were determined.
For reaming experiments, the control factors and levels of each parameter are given in table 3.

Some ternary nickel based alloys are developed to further improve the properties of binary systems by adding a second to meet some special demands.
Codeposition of W element has been of considerable interest because of its unique properties, such as excellent corrosion-, wear-, electrical- and high temperature resistant [4].
But unfortunately up to date, only limited investigations have been conducted on the effects of heat treatment and nanocrystallined structure on corrosion properties of Ni-B-W coatings.
Combined effects from several factors result in the lowest corrosion resistance for the coating annealed at 400 0C.

Introduction Porous silicon carbide (SiC) ceramics have been greatly anticipated as filters and catalyst supports, since among ceramic materials SiC has excellent thermal stability, good mechanical properties and corrosion resistance.
In filter applications of porous materials, porosity and pore size distribution are important factors that affect the performance of products such as permeation.
Thus, pore properties such as pore size and surface area, may be affected by dimensional changes.
In this study, the pyrolysis of polycarbosilane (PCS) and the role of filler in affecting the retention of micro/mesopores were investigated.
Conclusion Mesoporous silicon carbide with and without SiC filler was prepared from the pyrolysis of polycarbosilane (PCS), and the relationship between pyrolysis temperature, pore properties and surface area was investigated.
