Introduction Epoxy resin is the major matrix for composites with outstanding mechanical, thermal, and electrical properties.
In this paper, we report the mechanical properties of glass fiber reinforced epoxy with CNF.
There are many factors affect the improvement of composites, such as dispersion and surface treatment of CNF, which make the prediction of mechanical properties difficult.

Experimental study of mechanical and electrical properties of carbon nanofiber/epoxy composites.

Original residual stress, clamping force, cutting force and cutting heat are the main factors which causing the workpiece deformation.
However, prior works mainly focused on certain or some factors which affect the workpiece deformation.
The material properties of the workpiece and fixture elements are given in Table 2.
Material properties of workpiece and fixture elements shown in Table 2 are imported into the FEM.

Finally, as result of better powder spreading property, shape quality of the parts made by WPC is improved greatly and have good as well as with good laser sintering properties.
Wood-Plastic Composites (WPC) is green biological materials, it has many advantages such as good mechanical properties, high hardness, anti-aging, dimensional stability, easy to color, with wood texture and also recycled, the most important advantage is low-cost[4].
Fig.4 shows WPC SLS parts, as the result of nonuniform powder spreading process, the parts have bad quality, lays are not in these right places, affecting their shapes, making great error and losing their function.
The main factor of powder spreading influence is shape and particle size of filler.

Measurement and Calculation of Elastic Properties In Low Carbon Steel Sheet V.
The magnitude of the springback depends on elasto-plastic properties of the metal, parameters of the forming process and geometrical factors, such as shape, metal sheet thickness, etc.
However, many features must be taken into account such as stresses/strain evolution, texture development, changes in the plastic properties, etc.In response to these needs, NIST has carried out a comprehensive program to develop standard mechanical test and measurement methods for characterization of the properties related to formability of metals and springback, as described in [1].
Four-point bending measurement accuracy can be affected by internal friction in the instrument.
Among calculation schemes, neutron texture analysis provides a good average (global) estimate of elastic properties.

Generalized Self Consistent Scheme (GSCS) [11, 12] for a two phase heterogeneous material is used to compute the global properties (e.g., the coefficient of effective thermal expansion) of the homogeneous equivalent material (H) as a function of the local properties and volume fractions of the phases.
The macroscopic strength is dependent to the local strength by the concentration factor C (4) It depends as well as C on the local elastic properties of the phases and the temperature change.
The thermoelastic properties are computed with the GCSC and agree with experimental data (Table 1) [10].
Figs. 1 and 2 shows the change of RH and R’H with the composition of the phase by normalizing these factors by those obtained from the reference material containing 40% in volume of void.

For identifying the significant factors that affected the deposition yield, multivariate analysis of variance (MANOVA) and regression analysis based on partial least-square method were used.
HNT incorporation in polymer films has been shown to improve mechanical properties of functional films [8-10].
Titanium dioxide (TiO2) is used for coatings of metal implants because it presents antibacterial properties [1, 12, 13] as well as high biocompatibility [13-15].

Wear properties of mild steel are considerably affected by the process parameters of AFM.The effect of extrusion pressure, abrasive concentration and abrasive size during AFM on wear performance were investigated using a reciprocating wear testing machine.
Introduction Different machining operations will produce surfaces with different mechanical properties.
Hiroyuki et .al[4] found that surface properties like surface hardness, surface roughness, residual stress etc are affected by the cutting conditions like feed rate, shape of cutting edge and nose radius.
Jose Cherian et.al [5] reported that AFM will improve the fatigue properties of materials.
The abrasive concentration, interaction between abrasive size & extrusion pressure and the interaction between all the three variables are the major contributing factors for the increase in wear resistance during AFM.

As a control group for elastic properties of polymer scaffolds, rigid poly L-lactide scaffolds were fabricated.
However, these polymer scaffolds have rigid mechanical properties which result to fibrous cartilage formation [3].
That means compressive mechanical stimuli are very important factor in tissue engineering of regenerative cartilage [4].
To investigate the elastic mechanical properties of scaffolds compared with native cartilage, compressive mechanical tests were performed with a 50-Newton-maximum load cell at a cross- head speed of 0.1mm·min -1 using an Instron (Model 5567, Canton, MA).
Consequently, in vitro systems, namely in static environments without mechanical stimulations, the cell growth and ECM secretions of chondrocytes were not affected by intrinsic mechanical properties of polymer scaffolds

However, as the degree of compaction is affected by various internal and external factors, its accuracy is difficult to guarantee.
However, the degree of compaction is affected by various factors such as mechanical properties of soil, water content, compaction thickness, number of compactions, compacting machinery, test equipment, test operators and so on [1].
Such complex factors will inevitably make it difficult to guarantee the accuracy of the degree of compaction.
Physical Properties of Test Soil Sample Studies have shown that the compaction effect was strongly affected by soil quality.
