Introduction Seawater is a complex medium that not only contains chloride, but also various microorganisms that can initiate and enhance the localized corrosion process of metallic materials.
Material and Method Fly ash geopolymer concrete specimens were prepared by mixing fly ash with alkaline solutions and aggregates.

The ancient Chinese geomancy, although limited by the out-dated science and material technological methods at that time, still ran after conforming nature, changing and taking advantage of nature moderately, ran after the artistic conception of coordination and coorperation between human and nature, reaching the aesthestic ideal peak of harmony between human and nature, several thousand years before Western modern civilization.
At the same time, many shortcomings and flaws can be inspected in the Fengshui theory and methods, which elaborates the science spiritual necessity which must be sticked to in modern architecture design conversely.
With the advance of city, transportation, electricity, net, telecommunication technology,and architectural materials etc. with the combination of Fengshui theory and modern architecture design, the inheritance and creation on the ancient Fengshui theory must be prompted.

For discuss the node occur ductile or brittle failure, using the following method:(1)Using decreased stress - strain curve in the material model when the node occurs ductile failure and the stress of steel exceeds the material ultimate stress.
Model and node parameters 2.1 Material parameters and simulation modules The grade of steel is Q235-B for the structural steel, the yield strength is 215MPa, and tensile strength is 325Mpa.
Assuming the material is the two broken line model of ideal elastic-plastic.

Introduction The capability to synthesize diamond thin films using chemical vapor deposition enables the exploitation of the many unique material properties of bulk diamonds.
Diamond is an ideal material for an emitter, because it has a very low electron affinity, resulting in very low energy requirement to drive a visual display unit (VDU).

He actually tried to measure fracture toughness of structural steels when he noticed crack blunting due to plastic deformation at the crack tip, named Crack Tip Opening Displacement (CTOD) which was proportional to the loading, thus representing the CDF, whereas its critical value (CTODc) represents material property.
As a final step, non-dimensional variables Sr = s/sc and Kr = KI/KIc are defined, where it is supposed that Keff equals to the fracture toughness of the material, so that Eq. (2) becomes: (3) If the material is completely ductile, the structure fails due to plastic collapse at Sr = 1, while for fracture of a completely brittle material Kr = 1.
