Introduction Ceramic composites such as silicon carbide reinforced silicon carbide composites (SiC/SiC composites) are candidate materials for high heat flux components because of their high-temperature properties [1].
Because of the brittleness of the ceramic materials, FEM calculations were conducted assuming linear elastic behavior in two-dimensional plane strain.

Thirdly, Sr or Ca doped-LaMnO3 is a candidate cathode material of solid fuel cell [6].
Methods The crystal structure of a material at a given temperature and pressure can be predicted by minimizing its free energy with periodic boundary condition.
Thus for a cubic material:
This technique has been used for simulation of many kinds of materials [19-24].

Decreasing the combustor temperature will also impact on the need for costly combustor materials and thermal barrier coatings on the combustor liner, enabling a more resource efficient manufacturing.
Decreasing the temperature leads to significant benefit in terms of diminished NOx production, reducing the environmental impact of European air transportation, as well as a need for less temperature resisting materials for the combustor, contributing to a more resource efficient engine.
However, high temperature regions on the walls near the turbine combustion regions may occur, which raises the issue of high temperature resistant materials required for these regions, and / or of developing light and efficient cooling systems able to maintain the wall temperature below the material resistance limits throughout the turbine.
The key finding of these studies is that fully developed turbulence cannot be assumed in the turbine channels, so RANS numerical simulations are not suited for the problem, requiring more advanced LES numerical simulations.

NURBS-Based upper Bound Limit Analysis of FRP Reinforced Masonry Vaults Through an Efficient Mesh Adaptation Scheme Nicola Grillanda1,a*, Andrea Chiozzi2,b, Gabriele Milani1,c and Antonio Tralli2,d 1Department of Architecture, Built Environment and Construction Engineering (A.B.C.), Polytechnic of Milan, Piazza Leonardo da Vinci 32, 20133, Milan, Italy 2Department of Engineering, University of Ferrara, Via Saragat 1, 44122, Ferrara, Italy anicola.grillanda@polimi.it, bandrea.chiozzi@unife.it, cgabriele.milani@polimi.it, dtra@unife.it *Corresponding author Keywords: masonry vaults; FRP; NURBS; upper bound limit analysis; mesh adaptation.
According to Heyman, limit theorems of plasticity, i.e. static (lower bound) theorem and kinematic (upper bound) theorem, can be applied to masonry structures provided that the following conditions are verified: i) the compressive strength of the material is infinite; ii) sliding between parts is prevented; iii) tensile strength of masonry is negligible.
In order to take into account the main characteristics of the masonry material, each element is idealized as a rigid body.
For the sake of simplicity, the yield surface has been defined in the stress-space as the parallelepiped defined by the inequalities ,, where are material parameters corresponding respectively to compression strength, tensile strength, shear strength in the direction tangential to the interface midline and shear strength in the direction orthogonal to the interface midline.

Effect of incubation time on deposition behavior of Ruthenium films by MOCVD using (2,4-Dimethylpentadienyl)(ethylcyclopentadienyl)Ruthenium Masaki Hirano 1 , Kazuhisa Kawano 1 and Hiroshi Funakubo 1 1 Department of Innovative and Engineered Materials, Tokyo institute of Technology, J2-1508, 4259 Nagatsuta-cho, Midori-ku, Yokohama 226-8502 Japan Keywords: (2,4-Dimethylpentadienyl)(ethylcyclopentadienyl)Ruthenium, MOCVD, Ruthenium, Thin films, ABSTRACT The deposition mechanism of metal-Ru films including incubation time was investigated for Ru films prepared by metal organic chemical vapor deposition from (2,4-Dimethylpentadienyl)(ethylcyclopentadienyl)Ruthenium (DER) - O2 system.
I*TRODUCTIO* Ru film has been widely investigated as a promising electrode material for complementary metal oxide semiconductor (CMOS) gate electrode because of its high work function value of 5.0 eV and good dry etching properties [1].
This result suggests that the deposition with the short incubation time is a key point to make thin films with full cover and good surface flatness.

In all transitions the interfaces between the phases play an important role for the engineering of annealing.
As shown previously, the exciting challenge for the application of laser-induced temperature pulses is the engineering with strong undercooling or superheating.

This property extends the range of rotation speed, in which no material contact occurs between the journal and the sliding surface.
This material seems suitable as a short-lived alternative material to the high-temperature resistant superalloy.
This allowed the reduction of the abrasive friction problems of the applied material combination for the short time of experiments.
However, the materials and its coating are a key element for a long rating life.
