The enhancement is affected by many factors, such as filler size, filler volume fraction and filler dispersion states.
However all these theories related to the filler volume fraction only, and cannot give answers to how the other factors affect the properties of composites.
Such scheme investigates the mechanical properties of composites, focusing on not only the filler volume fraction, but also on the effects of filler size distribution and filler dispersion [5, 6].
Asymptotic homogenization We assume that the microstructure of composite is periodic and discuss the effect of fillers on the effective elastic properties.

The different amounts of Mg2+ and HCO3- affected the homogeneity and morphology of the coatings.
Main factors affecting the deposition were temperature of electrolyte and current density.
Introduction Titanium and its alloys are amply used for orthopedic and dental applications because they exhibit high mechanical properties and biocompatibility [1].
In order to improve its bone-bonding property, calcium phosphate coatings have been applied on to titanium implants [4].
However the temperature and pH also affects the solubility of calcium phosphates.

This research seeks to examine the premise that VMA is indeed a valid critical parameter and that the sole aggregate factor affecting the magnitude of critical VMA is the nominal maximum aggregate size. 2 Material properties It was decided that the asphalt used for the study would be a grade commonly used in China, an unmodified 70-A binder.
(2) Aggregates Because the focus of the study was how aggregate-related factors affect critical VMA it was essential to select aggregates that were measurably different using common aggregate tests, e.g., fine and coarse aggregate angularity, flat and elongated particles, etc.
Ideally, it would have been desirable to select aggregates based on specific (i.e., predetermined) test properties for comparison, but this is not practically possible.
For each mixes that became plastic (i.e., unsound), the volumetric properties were calculated at the critical point.
(3) Critical VMA is different in three AC-20 asphalt mixtures that mean graded type decision of critical VMA shows the important factors.

Abstract: Mechanical properties, especially fatigue strength, of ferritic spheroidal graphite cast iron might depend not only on the graphite size but also on the ferrite grain size, little systematic research has been made on these factors.
To clarify the influences of these structural factors as well as loading condition, fatigue tests have been carried out on ferritic spheroidal graphite cast iron with different sizes of graphite nodules and ferrite grains, under the axial loading with mean stress from -70MPa to 240MPa.
In many cases, fatigue determines the service life of machine parts, and therefore, a lot of researches have been made factors influencing the fatigue strength, such as graphite nodule size [1], graphite matrix structure as well as the mean applied stress [2, 3].

Factors such as density and confining pressure effect on the compressive strength were analyzed by comparing the experimental results under different conditions, the parameters of Cambridge model were worked out with the data from consolidation test.
To be the engineered barriers between parent rock and high level radioactive waste packaging, buffer/fill materials need appropriate mechanical properties so that it can buffer effect on waste cans from surrounding rock pressure and effectively prevent radionuclides overflow from cracked waste tank when the disposal site have geological changes.
Foreign Scholars has done a lot of research on the mechanical properties of bentonite.
Alonso[2],etc. carried out full-size multi-phase coupling in the underground labs based on the study of MX-80 bentonite and inquired mechanical properties of MX-80 bentonite in a variety of conditions.
But most of these studies are about water effects on bentonite and its mixture, factors like density and confining pressure which may affect the mechanical properties of GMZ bentonite are little involved.
