It is always possible to obtain tailored and enhanced mechanical/functional properties through the design of the cell spatial configuration and beam diameters [4].
In particular, compression tests were carried out on the fabricated lattice structures, and the influence of specific geometric factors (i.e., beam diameter, number of cells and cell rotation angle) on the mechanical performance was analysed.
Based on the results reported in the literature [4], the cell size and the beam diameter should be surely considered important factors.
The mechanical properties (e.g., the compliance and, hence, the crushing behaviour) were clearly influenced by the rotation angle as it affects the density distribution.

The technique proposed could be served as a reliable tool for cobalt-free maraging steel mechanical properties control and design.
In this paper, the authors propose a fuzzy identification for cobalt-free maraging steel mechanical properties modeling.
The influencing factors include chemical composition and heat treatment processing parameters.
The reason is that ductility-related parameters are more easily affected by experimental factors, such as tensile speed, specimen condition and dimension.
The influence of solution temperature on the mechanical properties of the steel is predicted and plotted in Fig.2.

Testing matching properties between ceramic substrate and coating-glass should consider the influence of surface roughness.
Introduction With the development of ceramic materials, zirconia is gaining recognition as a candidate material in dentistry owing to its good mechanical properties [1].
Compared with other dental ceramics, superior mechanical properties are due to the transformation toughening mechanism.
A zirconia-composed all-ceramic system comprises ceramic framework and coating-glass; therefore, anchoring strength between framework and coating-glass is a key factor influencing mechanical properties of all-ceramic system.
Then the microstructure of the system was observed and mechanical properties of the composite with different roughness were also tested.

Abrasive is one of the most important factors which affect the property of ECMP electrolyte.
However, the factors, which will influence the diffusion of metal ions, such as abrasive size, abrasive concentration and fluxion of electrolyte, were not discussed in that paper.
Since electrochemical technology is employed by ECMP, electric field becomes one of the most important factors which affect the quality of planarization [8].
Several properties of TiO2 and SiO2 are listed in table 1.
So the hardness is not the only factor which affects the quality of polishing.

But the problem is that the damage factor is subjective.
So how to determine the damage factor scientifically is a problem to be solved.
When the situation of the three former change less, the porosity and fracture are the main factors for resistivity of rock, different resistivity values mean different damage state.
The Relationship between Resistivity and Mechanical Parameters in the Uniaxial Compression Test In order to establish the relationship between mechanical property and electrical property in the process of rock damage, some marble specimens are selected to test in the uniaxial compression test.
Because resistivity is affected by moisture, temperature, the model established in this paper can only be used in the unchanged mechanical environment.

But for the mechanical properties of timber, which in compression, span and structure form is restricted.
In order to make up for the inadequacy of mechanical properties of timber, the field of timber structure usually considers the composite structure in the design, the TCC structure is one of the common composite structure.
The experimental results show that the rectangular notch and triangular notches have high rigidity and shear capacity, and the main factors affecting the effects of connection are the length of the notch and the type of nail.
Due to the above several methods of shear connection need a drill hole or excavated and weaken the mechanical properties of timber beam.
Factors affecting the effects of this kind of connection are the binder viscosity, the thickness of the adhesive and the production process of concrete (precast or in sight).

In-plane along the 0° carbon fiber direction, the carbon fiber controlled the mechanical properties and the strain rate effect.
It was observed that there are significant differences in the test results due to differences in raw materials, producing processes, testing conditions and configuration of the samples among other factors.
The dynamic compressive properties of the samples were determined by using the SHPB system.
In this sample direction, the mechanical properties and the strain rate effects were matrix-dominated.

The micro-nano sized tungstate materials characterized with fabulous superior properties in fields of luminescence [3-5], magnetism [6] and thermo-optical properties [7] and so on are the hot points of researches these years.
Factors controlling morphology The morphology a crystal grows depends on the cystal internal structure as well as the growing environment [21].
Other factors: The impurities in solution, which can affect solubility and solution property, change crystal habit to develop morphology.
Meanwhile the morphology is developing to be refered to an influence factor of tungstate properties [22].
The crystal anisotropy qualifies an excellent properties ranging of mechanical capacity, optical character, elasticity and magnetic performance in certain specific lattice direction, greatly satisfying some devices the demands of fine material properties.

It is also due to the inferiority of recycled aggregate which ultimately affects the concrete mixture either in fresh and mechanical properties.
Several papers on this matter investigated the quality of recycled aggregates and the factors affecting it.
The paper investigates the effect of recycled aggregate replacement percentages on key fresh and hardened properties of concrete with more focus on the effects on main fresh properties including workability retention, slump drop and rheological characteristics of the different mixtures.

The ratio of the thickness of the layers [1], the pressure in the deformation zone [2], the preparation of the surfaces [1, 3] and a number of other technological factors affect the value of the required deformation of the grasping during cladding.
In addition to the high adhesion strength of the layers, a number of requirements are imposed on the bimetallic strips of brass-steel-brass in terms of dimensional accuracy, mechanical properties and microstructure [16].
The relative reduction during cladding affects the bonding strength of bimetal layers, the nature of the microstructure, the size of the recrystallized grains, the mechanical properties of the strip, the dimensional accuracy [4].
To create the necessary exhaust properties of bimetallic strips, the optimum degree of deformation is in the range 0.45…0.60.
The factors were varied in the range T0 = 550...900°C, HpH = 2.0...4.0.
