The hybrid laminates are based on thin sheets of aluminum alloy and
plies of fiber-reinforced polymeric materials.
Nowadays, "lighter, thinner, stronger and cheaper" are the goals of materials science and engineering, especially in nanoscale age.

Introduction
Rubber filled with conductive materials can make into conductive rubber.
The dispersion of nanoparticles is not obvious after adding nano-materials.
The four kinds of carbon black rubber adding in nano-materials can improve the conductive properties of the composite material and its linearity.

Introduction
Functionally Graded Materials (FGMs) are advanced composite materials to protect large temperature gradients in a structure.
Usually, two materials are composed linearly by the rule of mixture through the thickness direction.
The deviation is dependent only on the Young's moduli of two materials [4].

Introduction
The transport of thermal energy across an interface between two different materials is playing an ever increasing role in thin-film and nanostructure device.
The Lennard-Jones parameters for materials B and C have been systematically modified: εB=α1εA, σB=σA, mB=mA, εC =α2εA, σC=σA, mC=mA, where α1 and α2 are proportionality constants.
Conclusion In summary, Nonequilibrium molecular dynamics (NEMD) approach is developed to investigate the thermal transport across a solid-solid interface between two different materials with an interlayer around it.
Moreover, interface thermal resistance determined by the interlayer materials does not depend strongly on the simulation system size.

Experimental investigation methods and techniques are used to obtain accurate information on the tension and deformation of materials.
Results underlying the limit stress state that aply to materials at this moment come from experiments on plain specimens and specimens showing stress concentrations.
Steel sheets are positively strain-rate sensitive materials which make distinct crosshead speeds generate different load–stroke curves even for specimens with identical shape and dimension [4].
Shear stress with mesh a) in Y-Z plane; b) detail of the area with stress concentrators The failure is going to happen perpendicular on the maximum principal stress directions, as seen in Fig. 6, which actually is the 45 degree section we considered critic and also the main minimum principal stress directions (because we have a ductile material, in case of brittle materials the failure might take place on the shortest section of the specimen).

And the bottom of the U-shape tube is close to ignition hole which is the top of fixed grating and was filled with some porous ceramic materials.
Firstly, biomass materials was fed into the domestic straw gasifier and then the biomass materials are lighted; secondly the thermocouple was inserted into the inside of gasifier through ignition hole to measure the temperature of the reaction.

As the computer science is developing rapidly, the search of technology of graphs has emerged in logic, linguistics, chemistry, electronics and some other fields of science.
A general introduction of breadth-first-search In computer science, graph theory occupies an significant position as it supplies simple but systematic modeling methods to a great number of problems.
The basic law of this algorithm has been introduced in a number of teaching materials.
