It is the passive earth pressure that keeps the mechanical equilibrium.
In this paper, factors of capacity of screw anchor are analyzed fully based upon the results in laboratory, the mechanism of soil mass failure is deduced, and the formula of calculation for the capacity of screw anchor is obtained.
Before loading, the imitative screw anchors will be embedded in sand with designated density and the properties of soil are shown in table 1 and table 2.
The size of the plate is an important factor of capacity which will develop with the diameter of plate.
When deeply embedded, structure plays an more important role in affecting capacity instead of weigh of soil[12].

The results of many scholars show that Cu-Cr alloys are an excellent aging strengthening alloy, using deformation and heat treatment method are an effective way to refine the grain, improve the uniformity of the structure, the mechanical properties and conductivity of the alloys [5-7].
In the thermal deformation process of copper alloys, DRX is a phenomenon that changes its structure and properties [8].

Introduction Zirconium dioxide (ZrO2) has broad applications for many engineering problems due to its outstanding thermal and mechanical properties [1,2].
Factors affecting the width and shape of the EPR signal in nanosized ZrO2 samples are described in [4-7].
The properties of these signals are a subject of forthcoming research.

Compression test on the porous scaffolds demonstrated that doping 10 mol% of strontium in HA has increased the compressive strength by a factor of two compared to the undoped HA with 1.81±0.26 MPa at 41% porosity.
Nonetheless, the mechanical properties of porous materials should be strongly affected not only by the intrinsic strength of the ceramic walls, but also by the pore structure [2].
Then, the porous scaffolds were characterized using FESEM and XRD while the mechanical test were conducted using Universal Tensile Machine.
A Lloyd LR10K mechanical tester with 10 kN load cells was used for the compression mechanical tests.
It was reported that bone ingrowth after 3 months of implantation could increase the mechanical strength from 2-20 MPa [4] resulting in improved in vivo mechanical performance.

The contour method, like most mechanical strain-relief based measurement techniques, can be affected by plasticity when measuring residual stresses of magnitude approaching the yield strength of the material.
Sections A and C were assigned identical material properties while section B was given a different yield stress and thermal expansion coefficient (see Table 1).
Table 1 The materials’ properties of the composite plate used for residual stress generation.
It is noteworthy that the reduced tensile stresses measured by the contour approach coincide with high values of stress intensity factor for such a crack, and therefore the contour measurement may well have been affected by plasticity under symmetric restraint conditions.

This research used poly(L-lactic acid) (PLLA) which was blended with poly(ɛ-caprolactone) to improve their mechanical properties [6] using oil-in-water solvent evaporation method with Tween 80 and Span 80 as emulsifier.
Pores in microcapsules also became the factor that influences the release of drugs from the matrix.
Conclusion In this research, microcapsules simvastatin was made using matrix from PLLA and PCL which were blended to get better mechanical properties.

Particular attention is focused on the influence of both grain interiors and grain boundary properties on the overall strength and ductility of the nc/ufc metals.
To particularly study the mechanical behaviors of the nc/ufc materials, as shown in Fig.1(a), and to investigate how the competition of grain-boundary deformation with that in the grain interiors determines the observed macroscopic stress-strain response and the overall ductility of polycrystalline aggregates by various properties of grain boundaries and grain interiors.
In a realistic physical sample of polycrystalline aggregates there are many factors which are relate to the initiation and propagation of intergranular fracture.
The distribution of grain geometry and grain property is also an important factor.

The main factors affecting the durability of foil bearings were material covering mating surfaces, bearing geometry, way of assembling the bearing, rotational speed and load.
The top foil is coated on one side with the coating made of a synthetic fluoropolymer that has excellent sliding properties.
This was indicative of the problem with a poor heat transfer from the slide surface of the bearing towards the bush affecting the operating conditions and the wear of the slide coating.
The material properties that were utilized in the model are listed in Table 1.
