Introduction Fracture mechanics is typically used for the prevention of failure by fracture in materials and structures containing defects.
The fracture toughness as compared to elastic-plastic material properties depends on the specimen size, crack depth, geometry and loading conditions [1].
Material and testing procedures The material is from pressure vessels and piping structures with Chinese designation 20g with the chemical composition of C 0.21, Si 0.34, Mn 0.59, S 0.03, Cr 0.04, Al 0.44 and Mo 0.05.

Introduction Thorough understanding of characteristic mechanical processes taking place on a microstructural level of materials is one of the essential steps to assure the materials can withstand the always increasing pressure to their utmost performance.
There are many methods dealing with the modeling of heterogeneous materials and one of the most widely used methods is numerical homogenization [1].
For materials with periodic patterns are the heterogeneities modeled as periodic unit cells (PUC), see Fig. 1.

It seems inevitable that in transistors of these dimensions alternative gate materials will have to be used and in particular high dielectric constant gate stacks (hi k).
These have enough similarity to silicon to envisage the use of existing silicon process equipment for device fabrication in these materials.
In the oxygen lean materials the spectra are dominated by the emission from the E-centre.

The technology used is simple and all the materials involved are local.
The plants can be constructed with 100% local materials and can be operated and maintained easily.
The materials and appliances are simple and familiar.
Development of more community projects after the successful demonstration at schools can trigger a new trend and thus will not only create the employment but many other economic activities like construction of tanks, support materials etc.

Material and method Jiaozhou Bay is located in the south of Shandong Province, eastern China (35°55′-36°18′ N, 120°04′-120°23′ E).
In April 1981, Pb contents were gradient decreasing from the west to the center of the bay, the reason was that Jimo Basin the west was one of the major agricultural areas (Fig. 2), and a large amount of plumbum-containing materials such as pesticide were applied in growing season of crops.
