The adsorption effectiveness and their factors of Ni2+ in aqueous solutions were simulated detailed using the adsorbents of the sludge incineration residue.
The simulation contents and the factors included the adsorption time, the pH of solution and the dosage of adsorbents and so on.
The purpose of this study is to simulate detailed using the sludge incineration residue as adsorbents to removal the Ni2+ in aqueous solutions and the adsorption effectiveness and their factors were discussed.
The solutions were agitated by mechanical shaking at a speed of 100 strokes／min.
The parameters affecting the sorption process, viz. contact time, pH and temperature were studied.

Compared to bulk lightweight materials, the hybrid laminates offer several advantages in mechanical properties, making them a good choice for lightweight designs.
While most studies examine the mechanical properties and fatigue behavior of these laminates, only few are dedicated to the damping behavior.
Sarlin et al. [7] studied the vibration damping properties of steel/rubber/glass fiber composite laminates.
A change of the metal material did not have a big influence on the damping properties.
One must also consider that the elastomer layer has a strong influence on other mechanical properties like bending stiffness or fatigue behavior of the FML.

Quantum mechanical calculations of the electronic structure of hydrogen storage materials have undoubtly deepened our fundamental understanding of their basic properties.
In this paper, we focuss on the latter aspects, we discuss the electronic and elastic properties of Haucke compounds of AB5 type (A=La or Y, B=Ni), in relation with their hydrogen absorption properties.
Substitutions at the La and Ni sites have been extensively used to modify the thermodynamic properties of LaNi5 and play a crucial role in the selection of the alloy for specific technological applications [12-15], since they affect the stability and the hydrogen content of the hydride.
These elastic and electronic effects affect in turn the hydrogen absorption properties relevant to applications.
Elastic properties.

Due to its excellent mechanical, biological and optical properties, it replaces the infrastructure of metal dental prosthesis in dental application and used as a structural application in engineering such as gas sensor, manufacture of cutting tools and refractories [1].
The mechanical properties strongly depends on its grain size where smaller grain size are associated with lower transformation rate but larger grain size above critical value are less stable and transform spontaneously from tetragonal to monoclinic [5].

Surface roughness is not as sensitive to grinding condition as in the case of metal and more affected by the difference in the material properties.

The kinds and characters of waterborne polyester is a key factor to decide the characters of WBPU.
Adding nano-sized materials into the system could endow the WBPU film better mechanical strength and other properties such as resistance to ultraviolet ray, heat insulation due to its small size effect.

There is little affect of NNCO/NOH on the resistance to water.

It is found that the shapes of the coarse aggregates do affect the tensile strength and failure pattern.
However, as is well known, the mechanical behavior of concrete is rather complicated, especially when it is under high strain rate.
In numerical simulation, concrete material is generally described as a homogeneous material with homogenized material properties derived from standard concrete sample tests[3].
However, concrete is a complex material, consisting of aggregates bounded by cement past, which makes the mechanical behavior of concrete rather complicated.
The reason is that different material properties of the three phases inside the concrete specimen affect the stress wave transportation.

The mechanical properties of the post-weld cold worked Al RSW were investigated, including the experimental results of fatigue.
The mechanical properties of the "as-received" Al 5052 are shown in Table 2.
Mechanical properties of Al 5052.
The ½ model had three different segments each with its own material properties, the segments are: weld zone, heat affected zone (HAZ) and base material.

The changing of material directly affects the design and manufacturing process.
At last, thermal stress and thermal deformation analysis are presented by taking nonlinear material properties into account, which provide some reference to evaluate the cooling capacity and structure design of exhaust manifold.
The main influence factors of the nodal temperatures are gas temperature and heat transfer coefficient.
Thermal Deformation and Thermal Stress Analysis Considering temperature variation, strain of elastomer is caused by two combined effect factors.
For the shortage of the mechanical properties of the material under high temperature, a fatigue analysis should be proceeded to verify whether the exhaust manifold meets the design requirements.

Introduction The alumina ceramics has various inherent properties such as high hardness, great thermal stability, chemical inertness and excellent wear resistance.
The properties parameters of alumina ceramics are listed in table 1.
The properties of alumina ceramic wafer Material Density (g/cm3) Vickers hardness (GPa) Bending strength (MPa) Fracture toughness (MPa·m1/2) Alumina 3.7 20 320 3 There are a lot of variables and virtually all these variables affect the erosion results.
In the experiments, four main factors were chosen, i.e. jet impact angle, standoff distance, water pressure, abrasive particle diameter.
This is because the water pressure directly affects the erosion kinetic energy of the abrasive particle.

In order to get excellent mechanical properties, deposited alloy system and alloy content are regulated according to the working conditions of the rollers.
Mechanical properties of the deposited metal may be affected by dissolving and precipitating of carbides and nitrides during arc welding.
For example, in this work changing vanadium content only partly improved mechanical properties.
In order to get perfect combination of mechanical properties, we should also make efforts in microstructure refining, composition uniformity and inclusion control, etc.
Crack length is related to many factors of deposited metals.
