The optical properties, microstructures and photoluminescence spectra of the fabricated Ho:YAG ceramics were investigated.
Compared with single crystal, Ho:YAG ceramic laser materials have several advantages such as improved mechanical properties, increased range of composition, fabrication of large size and high doping concentration, mass production as well as lower cost[6-8].
The microstructures including grain boundary, grain size and residual pores are considered as the main factors affecting the transmittance [11].

To investigate errors caused by gravity, it is essential to figure out the most influential factor.
Introduction The accuracy of a heavy-duty CNC machine tool is determined primarily by the geometric properties of machine tools.
Geometric accuracy is one of the critical factors in determining the machining quality.
And then, further research on the compensation of the key factors can be carried on.

The tests with different properties were analyzed to check the best results and find the most suitable material effect and force difference due to material densities, wall thickness, and other properties.
These properties show large differences in results, such as a 20% strain increase in the Quarter cubic infill.
The general concept of this article is to determine the best possible infill for use while checking the mechanical properties and effects of each infill at different densities.
I made this possible by reducing the factors that could influence the results.
This can be helpful if the properties that each shape shows remain the same, as you can have greater control over the properties.

This paper lists the results of a series of tests on samples, made of VC, SCC of equal strength, and SCC with identical w/c factor.
Subsequently, a comparison of the mechanical characteristics is made, revealing important differences regarding several fracture parameters.
Introduction Extensive research has been carried out on fresh, hardened and transport properties, as well as on durability aspects [1-3] of SCC, showing that the substantially different composition, opposed to VC, sometimes causes an altered mechanical behaviour.
Influencing factors for these differences are: a dissimilar specimen size, shape and self-weight, diverse FPZ length, varying stress states near the crack, and potential storage of elastic energy during testing.

The last two factors are mainly influenced by the machine selection and the knowledge of factors influencing process deviations.
The elastic material behavior has already been named as one of material parameters affecting springback.
The observed mechanical properties are summarized in Fig. 1a.
This data set corresponds quite well with what can be expected due to the mechanical properties.
Different parameters, e.g. materials, orientation of the bending axis compared to the rolling direction and the chosen bending concept proved to be significant impact factors affecting the springback.

But there are many formulations of concrete, which provide varied properties.
Physical and mechanical properties of the artificial sands are shown in Table 2.
Four factors are water-cement ratio, flyash content, admixture content and sand ratio.
Table 5 shows the details of four factors and three levels orthogonal table.

Electroless nickel plating has been used in many industrial applications due to its outstanding deposition properties, such as excellent corrosion, wear resistance and deposit uniformity [3].
The purpose of this work was to develop electroless plating different combinations of Ni–Cu–P onto polyester fabric and investigate the properties of plated fabric, such as the surface morphology, crystal structure, composition, surface resistance and EMI shielding effectiveness were also studied.
Results and discussion Surface morphology The surface morphology of metallic fabric may affect their electrical, mechanical, and optical properties.
Tinted fabric Figure 1 Scanning electron microscopy image of plated Fabric Electromagnetic shielding The electromagnetic shielding of electroless plated fabric was affect by a variety of factors, especially for the thickness, uniformity of the metal layer and sort of metal.
For the same metal, the thickness of the metal layer is the most important factor and for the same weight increasing rate, the sort of metal is the most important factor.

Comparative analysis of the effect of the Mechanical Properties of inner set CFRP round pipe to components ; Studying on the effect of Mechanical Properties of Square Steel Tubular High-strength concrete inner set CFRP round pipe under with different arrangement ratio of CFRP and strength grade of concrete.
Square Steel Tubular concrete have high sectional flexural stiffness, simple joint construction and great bearing capacity,at the same time it’s defects of mechanical properties are existing[1].
In the past, studying on mechanical properties of components under uniaxial loading, finite element analysis of Square Steel Tubular High-strength concrete inner set CFRP round pipe flexural members joints was seen occasionally.
The same flexural members, different structure form, it’s mechanical properties will be various greatly, so the author will use the Finite Element Method, based on reasonable stress-strain constitutive model of the material and the failure criterion of the composing materials, simulate and analise the mechanical properties of Square Steel Tubular High-strength concrete inner set CFRP round pipe flexural members.

Introduction The properties of carbon nanotubes are very excellent.
Currently, researches in the domestic and foreign are mainly focused on cement paste or mortar, but seldom on the properties of concrete composite with few carbon nanotubes.
As modern engineering structure is mainly based on the concrete structure, whether concrete composites with CNTs can have good mechanical-sensitive properties should be further researched.
So taking other affecting factors and mechanical enhancements into consideration comprehensively the optimal content of CNTs is 0.2% and 0.3%.
Cement based composites containing a small amount of carbon nanotubes perform well in mechanical-sensitive property, and the experimental results demonstrate that mechanical-sensitive property is influenced by two factors mutually.

The mechanical properties of the tensile bars with lattice structures are compared to fully dense tensile bars.
Tensile bars are produced by conventional casting to compare the mechanical properties between SLM and casting.
The resulting microstructure and mechanical properties are comparable with those of material produced by conventional methods.
Due to the complex processes, a lot of influence parameters exist, which affect directly the density and surface roughness of the part and so consequently the mechanical properties.
To compare the mechanical properties of the SLM parts with parts produced by conventional techniques multiple tensile bars were also created through casting.
