Although the inclusion of fillers may improve several mechanical properties of polymers, some studies also reported that some important properties, such as the tensile strength, can be adversely affected by the inclusion of the nanofillers in the polymer[14].
Mechanical properties of Epoxy Nanocomposites Reinforced with Alumina Nanoparticles This section presents and compares the results from some authors with respect to some important mechanical properties of epoxy nanocomposites reinforced with alumina nanoparticles, namely: tensile properties, toughness and flexural properties.
As previously referred, factors such as the extent of adhesion of the filler to the epoxy resin, the dispersion state of the filler in the epoxy matrix, as well as the shape and size of the particulates fillers and also the quantity of added fillers have been found to affect notably the mechanical properties of the epoxy composite[20].

In micro-EDM, two poles maintain non-contact and mechanical stress is not introduced.
The following discusses the factors of the micro-EDM process, which guarantees machining precision.
The discharge gap and its deviation are related to processing factors; thus, experimental research should be performed.
It is because reduction in insulating properties in the low resistivity makes the conductive enhance, and the short-circuit is very easy to happen, then the process is unstable and it is like to cause changes of micro-hole diameter.

However, the factors influencing the damage behaviour and the degradation of mechanical properties under real applications are numerous.
It is assumed that all planes perpendicular to the isotropic plane transversal to fiber direction possess the same properties [10].
These four material properties are essential for any non-isotropic engineering stress calculation, FE analysis etc. [10].
As a matter of fact, the applied load speed affects the measured mechanical properties and consequently any subsequently performed fatigue-life calculation.
Mechanical properties in fiber direction, transversal to fiber direction and under shear loads were created in experimental tests.

Introduction In the past decades, there has been a growing interest in high performance engineering and industrial applications of metal matrix composites (MMCs), because of their advanced mechanical properties.
Titanium and its alloys have been known as the ideal matrix for developing advanced metal matrix composites for aerospace applications because of their superior elevated temperature properties [1].
The results will be later correlated with the mechanical properties, as determined by the small punch testing of the Ti metal matrix composites.
The small punch tests apply a small volume of material of 10 mm diameter and 0.5 mm thickness, in determining its mechanical properties.
The results of the small punch tests are expected to be greatly affected by the morphology and distribution of the reinforcement phases.

Factor that affects the good adhesion of geopolymer with wood surface was due to the successful penetration of geopolymer into the wood pores which subsequently establish the physical mechanical interlocking and chemical bonding between these two surfaces [26].
Shrinkage and expansion behaviour of different Si and Al ratio can affect the properties of the coating materials.

As we know that some processing parameters will affect the stress needed to move dislocations, thus determine the bake hardening properties.
Among them, the pre-straining, ageing temperature and holding time are the most important factors.
However, limited researches of cold-rolled CMnSi dual phase steel have worked on the bake hardening properties.
Therefore, the effect of pre-straining and ageing on bake hardening properties of dual phase steels was investigated in this paper.
It is believed that grain size and morphology of ferrite and martensite affect the mechanical properties of dual phase steel; these complex structures give the steel excellent combination of strength and ductility.

Its quality is dependent upon glass material selection; there are many factors determining glazing material selection, which might further affects the building safety and energy savings.
The physical properties of glass building materials damaged by fire have been studied [1].
Based on relevant literature review and the opinions of five experts, ten factors affecting green glazing materials selection were simplified into an assessment framework of green glazing material selection multiple decisions.

Optimization of the flame-spraying process and improvement of properties of a NiCrBSi coating by heat treatment J.
Subsequent heat treatment of the NiCrBSi coating showed significant adhesion strength increase and improvement of microstructural properties. 1.
Quality of adhesion bond with a substrate greatly affects the performance of coatings.
A final stage of producing NiCrBSi coatings is heat treatment, which should improve the properties of coatings.
The structure analysis indicates strong inhomogeneity of the NiCrBSi microstructure prior to heat treatment and essential improvement of the coating properties after heat treatment.

In the metal plastic forming process, ductile fracture is an important factor influencing the forming properties of materials, and the ductile fracture criterion can effectively predict the moment and location when the material fracture.
However, the material constants in ductile fracture criterion is related to many complex factors such as material properties, forming process, stress and strain state.
The tensile properties and the fracture strain of the material can be obtained through uniaxial tensile test or plane-strain tension tests, so the stress, strain and other related parameters in criteria can be converted into known constants of tensile properties combined with relevant plastic theory knowledge, then integrating the Eq. 1 to determine the material constants in criterion.
According to the number of unknown parameters in the Cockcroft-Latham, Brozzo, Oyane, and Clifte criterion, Takuda et al. [4] carried out uniaxial and plane-strain tension test for sheet specimens, obtained the tensile properties (including anisotropic coefficient) and fracture strain.
However, for the general material in the forming process, it is susceptible to the drawing speed, mold clearance, sharpness of the punching tool and other process factors, resulting in the material tending to appear necking, and the deformation path is not same after the material necking.
