When conducting numerical analysis in this paper, Both the 6m high embankment fill and the 25m thick soft soils as well as 3m thick hard clay were considered as Mohr-Coulomb materials, while the horizontal reinforcement, pile and pile-cap were considered as Linear-Elastic materials.
All of the material parameters are listed in Table 1.

As far as the spherical and cylindrical cavities problem is concerned[6-7], many solutions have been obtained for cavities in various types of materials.
Especially the hole shape changes faster when the material around hole enters into a state of plasticity. 3) When the materials around whole hole enter into plasticity.
When the materials enter into plasticity.

In the present paper we report on the design and production of a new class of alumina-copper functionally graded materials (FGM) which have technological potential for application in automotive brake disks.

In the bonding interface of 3Y-TZP and SUS440, the Ti-Cu (brass) powder/sheet was used as bonding materials.
Additionally, brass sheet-Ti powder and Ti sheet-brass powder were applied to be two kinds of bonding materials.
The materials were both cut off by the unit length of 10mm, and the section was polished with the #600 and #1200 sandpaper respectively.

The static properties of Prestressed arch support single / double-layer reticulated shells Hong Zhang1,Jiantao Dong2,Jun Zhao3 1,2School of Science, Chang'an University, 710064, Xi'an, China 3 State Key Laboratory of Geomechanics and Geotechnical Engineering,Institute of Rock and Soil Mechanics,Chinese Academy of Sciences, Wuhan ,Hubei 430071, China azhanghong_2000@163.com,bjtchd@163.com,cjzhao_rsm@163.com Keywords: prestressed arch, ANSYS, performance, static properties Abstract: Following an analysis of static performance of the prestressed arch supported by a single / double-layer reticulated shells ,Single/double -layer of shell bearing surface structure of the node center point displacement, upward displacement of the structure, the structure raised some pressure, sunken part of the tension.
Itroduction Prestressed arch support single-layer shell structure beautiful, simple and neat, rods and small nodes, but less able to cross (not more than 60m), mainly by the stability control structure design, Prestressed arch support and strong double-layer structure and materials across the economy, mainly by the strength of control structure design, but the bar, multi-node, visual effects worse, Therefore, in the span (more than 60m) structure will be single/double layers shell combine to form a new structure, that is prestressed arch support single-layer shell, which can take advantage of two structural forms advantages.
