As a set-up of the test bench, several preliminary experimentation measurements have been done to assess factors of interest such as sensitivity and a correlation index.
To this regard, most of the multi-material parts testing found in literature normally focus on the evaluation of dimensional properties (being it at the macro or micro scales), as well as of mechanical properties, such as strain-rate dependence and maximum yield strength [19].
At the same time, additional series of regulations regarding the determination of the mechanical properties of test samples will apply, such as ISO 178:2019 Plastics (Determination of bending properties)[24], ISO 527-1:2019 Plastics (Determination of tensile properties- Part 1: General principles)[25], and ISO 527-2:2012 Plastics.
Concerning resistivity measurements, significant differences have been detected for some of the printing parameters that have been analysed as factors of study.

There are many factors of affecting throwing ends wear.
By studying the maximum load and average load of the vertical shaft impact crusher throwing ends, the paper [1] shows the law that rotational speed affects wear by load change.
Thus, the change of stone impact number, impact direction and impact location will bring a different distribution of load among the three throwing ends, which affects the wear uniformity and life of throwing ends, so the further researches are necessarily.
The impact role of stones is result of the stone movement in the rotor flow field, the influence factors are so more and the randomness is so large in the stone movement that the observation and experiment are difficult to carry out.
To throwing ends, the material is set for steel, the elastic modulus 2.07e +011 N / m2, the density 7801kg/m3 and Poisson's ratio 0.29; To the stone, the feed size is less than 55 mm, the property is set for limestone.

Introduction The advantage of abrasive treatment in magnetic field is a complete mechanization of finishing operations of details with complicated contour such as rotary bodies made of materials with different physical and mechanical properties.
Adjustment parameters and treatment regimes are the factors determining forming regularity in the process of magnetic-abrasive finishing.
Regime factors include: ratio of detail speed and polarized rotating electromagnets, value of magnetic inductivity in the working clearance.
Factors characterizing cutting properties of magnetic-abrasive powder, its ability to self-sharpening, accuracy of the pattern original form also influence on the accuracy.
Physical and mechanical properties of materials surface layer after MAF.

In fact, the undesirable low mechanical properties microstructure resulting from melting and re-solidification is absent in FSW welds leading to improved properties in some alloys [7-8].
Aluminium and magnesium are most often welded using alternating current, but the use of direct current is also possible, depending on the properties desired.
Here the factors influencing the weld strength are Rotational speed, Welding speed and axial load, we have considered three factor levels and by taguchi principle these parameters are converted into L9 orthogonal array.

Specific properties of building envelope in energy passive standard.
However, it would be misleading to think that the indoor climate – external climate interaction is affected only by glazing area size considering the transparent parts of building envelope.
The correct solution of window structural parts and window embedding in building envelope is a relevant property of quality window.
Also other factors (e.g. aesthetic solution, possibility of additional clap-net application, etc.) are to be taken into consideration in the decision making process.
Considering all the factors the detail of window imbedding in building envelope was realized according to model 2.1.2 (Figure 8).

Many experiments have been carried out with the aim of improving the mechanical properties of the AZ31B alloy.

However, still the mechanical tensile properties of Mg AZ31B are the same in both.

Larger grains and dimples in the furnace cooled samples as compared to the air-cooled samples did not affect the tensile and hardness properties in very thin sheets. 6.

Introduction A lot of practice and research shows that gun muzzle disturbances is an very important factor to affect firing accuracy.Unbalanced of recoiling parts,stiffness,clearance and backlash of elevating mechanism would serious affect muzzle response,causing significant low-frequency vibration of tipping parts about trunnion,and firing accuracy of naval gun would be affected.In the literature 3,a naval gun is analyzed with nonlinear dynamics method,and the interaction between cradle arc and main gear of elevating mechanism is defined by torsion spring constraint.This approach is difficult to accurately simulate complex three dimensional contact/impact between cradle arc and main gear of elevating mechanism and it’s effect on muzzle disturbance.In the literature 4,the author considered the contact between cradle arc and main gear of elevating mechanism based on multi-body system dynamic model,but each part of gun is dealed with rigid body,especially barrel,which’s flexible has great
Engagement process of cradle arc and main gear of elevating mechanism Elevating mechanism is drived by handwheel or power,controling pitching parts movement of cannon.The structure sketch of naval gun shows in Fig.1.Strong impact between cradle arc and main gear of elevating mechanism will cause slight vibration of tipping parts about trunnion,considering factors such as transient high impact load, backlash of elevating mechanism and elastic deformation of gearing.This is a main factor caused muzzle disturbance,so the impact of cradle arc and main gear of elevating mechanism must be studied and simulated.In order to be more close to the actual, precise models of parts,mechanical model of impact and the corresponding parameters of physical properties should be considered.
Conclusions The precise 3D models of involute straight tooth gear and arc were constructed.Considering the contact between cradle arc and main gear of elevating mechanism,the dynamic simulation is carried out.The results shows that simulation results of contact model can be more fit the actual than equivalent stiffness model’s.The effect of random factors such as clearance and backlash,testing and validation related naval gun’s dynamic parameters should be further studied.

In view of the main factor, getting the ball contact force distribution.

The contact stress between ball and ball screw groove is bigger than between ball and nut, and the difference of contact stress leads to different characteristics,which is one of importantly reasons that the ball screw groove wear faster,as influences the effective life of ball screw pair.Therefore,it should take contact factors into account to design ball screw pair.

Chemical Protection of Masonry Material .Most of the masonries in ancient architectures are exposed to the outdoors, due to atmospheric changes, wind and rain erosion, microbiological corrosion and properties of masonry material itself and other factors, they are inevitably destroyed by weathering.
Chemical protection for masonry materials requires the surface of masonry cultural relics can inhibit the penetration of external water and without affecting the internal moisture to escape.
Requirements for material performance are close to the physical and mechanical properties of reinforced masonry, and in accordance with requirements of good adhesion, low viscosity, good irrigation, good penetration ability, can be cured at room temperature, freeze-thaw resistance, water resistance, etc...

Pore-structure and water transport properties of surfacetreated building stones.

Traditionally, hot mechanical working has been one of the available procedures to minimize heterogeneities.
This limits the possibilities of mechanical homogenization during hot working.
Nevertheless, the same factors intervening in the initial grain heterogeneity can affect grain size evolution after deformation, that is, the TiN particle distribution.
In this case the proper selection of the recrystallized mean size is a key factor.
As shown in Fig. 8, the hardness levels are similar to those found at higher cooling rates, when fully bainitic structures form, but the presence of coarse grains that can impair toughness properties is significantly reduced (Fig. 10).
