Many manufacturers use important safety factors to design structures.
In 2002, Cartié et al. [8] study the influence of resin and fiber properties.
Many factors act on this behaviour, such as the loading level, the frequency, etc.
Concerning the damage development, many properties of the materials act on it.
We decided to measure the health of the samples before impact, three-dimension geometry of the damage produced by impact, and residual mechanical properties.

The mechanical properties of 3D printed materials in FFF technology depends on various parameters and the literature suggests that infill pattern and infill density are the parameters that most affect the mechanical properties of 3D printed parts.
In this context, 3D printers can use a wide variety of materials with different mechanical properties, visual appearance and finishing precision [3].
The mechanical and physical properties of PETG filament are presented in table 1.
All factors and their levels can be seen in Table 4.

In the process of machining, one of the main factors affecting machining tool wear is friction.
Introduction In the scope of the current work, it is proposed to use dummy variables for an assessment of a large number of attributive factors characterising friction.
Also, a significant outcome of this study is the determination of coefficients characterising the impact of each factor on the result separately and an opportunity of ranking the factors by the level of its impact on the outcome variable.

Dental zirconia ceramics have been widely used in dental restorations due to their superior aesthetical and mechanical properties.
Therefore, a better surface quality will be achieved with the combination of lower spindle speed, cutting depth and feedrate. 1 Introduction Because of their superior aesthetical and mechanical properties, dental zirconia ceramics have been widely used in dental restorations for implants, bridges and crowns [1-3].

Table 1 shows the composition of the sintered dental zirconia ceramics workpiece material and the mechanical properties are listed in Table 2. 2.2 Design of Experiments.
When the spindle speed is 4500 r/min, the interaction between adjacent abrasive particles is the predominant factor which affects the surface roughness.

A variety of factors could affect the coefficient, such as aggregate type, curing time, water/binder ratio, cement type [3,4].
However their researches were not mainly concentrated on solving mechanical properties, but thermal properties.
Micro-pore texture directly affects mechanical properties of concrete [6,7].
Porosity can't fully reflect the influence of pore radius on thermal properties.

In the analyses carried out in the present study, material properties at 300=T K and 5.786=T K are used for mechanical and thermal loading problems, respectively.
These properties are given in Table 2.
The continuous distribution of material properties are incorporated into the finite element model by specifying the material properties at the centroid of each finite element.
There is a boundary layer near the stress - free surface which affects the stress intensity factors.

Factors such as neutron irradiation, corrosive environment, and temperature gradient – all of these aspects tend to lower the service life of the main structural components of the reactor such as core, its containment, main service lanes, etc.
Current paper reports the change in the microstructure and mechanical properties of the stainless steel witness samples of IVG.1M reactor that had been irradiated by neutron fluence for about 40 years.
Moreover, properties of the metal indicate good correlation and do not deviate much for this specific type of steel.
Moreover, the mechanical properties correlate well with the values presented in the literature for this specific type of steel.

The mechanical and electrical properties of the plate are considered for a class of functional forms for which closed-form expressions for the moving crack tip electromechanical fields are obtained.
The properties of the NPM plate vary along the y-axis (Fig. 1).
Assume that the material properties are in the same proportion so that (c44, e15, ∈11, ρ)=(c0, e0, ∈0, ρ0)f(y).
(12) The asymptotic fields near the moving crack tips can be expressed in terms of the field intensity factors in the moving coordinate system.
Therefore, material non-homogeneity only changes the magnitudes of the stress and electric displacement intensity factors.

The mechanical properties of the solder layer have not been studied in practice and in the calculations, we will assume that the properties of the solder are equivalent to the properties of pure silver.
Properties of sapphire were taken from [19-20].
The presence of the above factors leads to the need for an individual calibration of each strain gauge.

Previous studies reported that the mechanical properties of concrete are enhanced when FCS is used in place of natural aggregates.
However, water absorption of FCS aggregate is higher than that of natural aggregate, which may affect the mechanical properties of the pervious concrete.
Moreover, pervious concrete with 100% FCS aggregate also showed reasonable mechanical and infiltration properties.
However, the strength properties of the pervious concrete were affected negatively by the increase in FCS aggregate content.
