Coupling electromagnetic field makes the properties improve.
There are many factors affecting the rheology behavior of Ni/TiO2/SDBS EMR fluid , such as particles radius, concentration, shear ratio and loading magnetic field, electric field or electromagnetic field and etc[8-10].
This paper focuses on the research of properties of Ni/TiO2/SDBS EMR fluid with different shear ratio under different electric field, magnetic field and electromagnetic field.
It is showed that particle size is main factor for EMR effect, a smaller size of particle can improve the properties of EMR.

The aramid paper exhibits numerous excellent properties such as good thermal property, flame resistance, electrical insulation transformer, high dielectric strength, good mechanical properties, and was applied widely in many fields including electrical insulation, aero wing, radome, honeycomb panel, etc [4].
The mechanism properties of aramid paper are showed in Fig. 4.
The dates show that the aramid paper with a better strength and elongation are prepared, and the proportion of fiber/fibrid is the main factor for affecting the mechanism properties of aramid paper.
So, the proportion of fiber/fibrid is very important for endowing the aramid paper with excellent mechanism, the short aramid fiber is the matrix affecting the strength and thermal property and aramid fibrid has excellent adhesive property for binding.

By means of mechanical properties test and microstructure observation，the relationship between mechanical properties ,microstructure graph of core-shell Ni/TiO2 group particles concentration of EMR and different electric field, magnetic field or electric- magnetic field have been researched.
It is found that with increasing of particles concentration, the properties are increased.
There are many factors affect the properties of Ni/TiO2 group EMR fluid [4.5], particles concentration is one of most important factors [6.7].
The properties and microstructure under electric field, magnetic fields or electromagnetic fields are direct affected by particles concentration.
This is due to the nanometer core-shell particles into the fine chain in low concentration, chain interference each other are low, mechanical properties of EMR are low.

But because the vitrified microsphere we use of which much exists on the defects of high dry density and bad insulation effect, it analyzed deeply kinds of factors which influence on the physical and mechanical properties of vitrified microsphere insulation mortar, making use of orthogonal experiment to optimize the composition materials of insulation mortar.
The orthogonal test results show that the most influential raw materials factors to mortar insulation properties and 28d compressive strength followed by aggregate, polypropylene fiber, fly ash and latex powder.
On this basis, for single-factor test, through analysis of single-factor test, has the basic components of a variety of content on the main properties of glass bead insulating mortar effects of trends.

Therefore workability and mechanical properties of mortar in meeting conditions, should be appropriately increased aggregate amount and water cement ratio.

The addition of MCC to cement-stabilized soil resulted in a reduction in hydraulic conductivity due to its water absorption properties, although it did not significantly improve mechanical properties.
Overall, while MCC alone had limited impact on mechanical properties, SB emulsion showed promise for enhancing toughness and ductility.
This study aims to investigate the potential of MCC to enhance the mechanical properties of SB modified cement-stabilized soils.
Several factors could contribute to this phenomenon.
The addition of MCC to cement-stabilized soil resulted in reduced hydraulic conductivity due to its water absorption properties, but did not significantly enhance mechanical properties.

Additionally, to reduce structural self-weight without excessively affecting the slab thickness (which could represent a major issue in this applications), lightweight concrete represents a preferable solution.
The properties at the fresh state are summarized in Table 1.
Since the two set of tests were carried out at different times, the mechanical properties of concrete changed consequently.
This effect is mainly due to the smaller concrete cover to diameter ratio for P-specimens and also to the significant increase in the mechanical properties of the concrete (as indicated by the increase in the compressive strength), which probably resulted in a more brittle behavior.
The decrease in the bond properties which can be expected for a lightweight concrete is to some extend compensated by the increase in the properties of the Interfacial Transition Zone, which is typical of self-compacting concrete.

One commonly used material in 3D printing is Acrylonitrile Butadiene Styrene (ABS) due to its favorable mechanical properties and ease of processing [5,6].
One of the most common factors is the stress intensity factor.

The review also delves into the structural properties of these blocks, including their compressive strength, thermal insulation capabilities, and resistance to environmental factors such as moisture and temperature fluctuations.
The strength of these blocks is influenced by several factors, including the type of clay used, the concentration and type of alkaline activator, curing conditions, and the inclusion of any additives[22]. 3.1.1 Key Factors Affecting Mechanical Strength: i) Type of Clay: The composition of clay, particularly its aluminosilicate content, directly affects the geopolymerization process and the resulting mechanical strength of the blocks.
Key Durability Factors: 3.2.1.
The prices of alkaline activators can fluctuate based on market conditions and supply chain factors, which can affect the stability of production costs and pricing of the final product.

Considering the complex hydrothermal environment of the composites structures in these fields, it is very significant to analyze the mechanical properties and behaviors of the composite materials.
According to the references [6] and [7], the properties of unidirectional fiber-reinforced composite, especial tensile strengthen and compression strengthen, are mainly affected by hydrothermal factor.

MECHANICAL PROPERTIES OF ZIRCONIA TOUGHENED ALUMINA COMPOSITES WITH TZP PARTIALLY NANOSTRUCTURED SINTERED BY LIQUID FASE.
In the Table 1, it can observe the values of relative specific mass, linear retraction and porosity and of the mechanical properties of alumina - niobia ceramics and of the composites of ZTA.
Some factors as the solubility decrease of MgO in the net of alumina and as well, the presence of small quantities of niobia up to 5 % in weight in zirconia´s ceramics, contribute for a continuous decrease in the specific mass of the material[12].
These results show that the zirconia acted as an inhibiter of the grains growth in the ceramic composite, but that did not result in a considerable increase in the mechanical properties, mostly when compared to alumina - niobia.
For this striking influence of the vitreous phase and of niobia in the present zirconia in these ceramic composites, it was not possible to relate the effect of the grains size to the mechanical properties of this material.
