The combination of elastic stretching and compressive stress generation causes the material to develop a compound, convex curvature on the peened side.
The values of process parameters which produce the required surface curvature and material strengthening in a given super-element are identified experimentally by processing sample-plates of 100x19x2mm in size made of equivalent material as the final part and measuring the geometry changes [4].
Having identified the relationship which describes the stress variation through the material thickness it becomes possible to determine the integral distribution of deformation forces and the corresponding bending moments through the plastic deformation of the material by forming equations (16) and (17)

Fabrication of SiC and SiC/ aluminum-silicon Composites from Rattan Charcoal Yung-Jen Lin*, Xiao-Wen Lo Department of Materials Engineering, Tatung University, Taipei 104, Taiwan * yjlin@ttu.edu.tw (corresponding author) Key words: SiC, composite, rattan, bioceramic, Al alloy Abstract.
Introduction Fabrication of ceramics with structures of bio-organics has attracted much attention in recent years.[1-3] Many bio-materials such as bones, shells, fish scales and several kinds of plants are used as templates for bio-structured ceramics.[4-6] Because the bio-materials contain carbon, carbides and their composites are the most popular ceramics fabricated from bio-materials.
During the synthesis, the structure of the bio-materials is retained.

In specific conditions of temperature and pressure, the aluminosilicates may, in strong alkaline environment, react among themselves, giving place to the formation of stable materials of high mechanical strength, able to support high levels of temperature and resistant to acid action.
Introduction The alkaline activation is a policondensation reaction that provides materials with high chemical resistance and excellent mechanical behaviour.
The raw materials for this reaction are mainly the aluminosilicates that form more than 75% of the solid part of the terrestrial crust.
A plan has been organised following the above-mentioned objective: � Determine the sufficient time of exposure to temperature � Determine the ideal temperature for dehydroxilation � Characterize materials in different phases of both processes Experimental In this research work, commercial kaolin from the area of Esposende in Northern Portugal has been used.

Introduction Ultrasonic machining USM is a combination of the grinding material’s oscillation, the ultrasonic oscillation and the cavitation.
The vibrator consists of the piezoelectric material and the metal (brass in this article) which are pasted together, and it is used to generate resonance.
Table 2 Nature frequency and resonant frequency of vibrator (Hz) 35-tooth vibrator (Thickness of ceramic disc is 0.5mm) Mode A Mode B Difference of frequencies FEM 46033 46033 0 Experiment 39235 39225 10 It is seen that the theoretical results and the experimental results of the frequency are different, because of the effects on the frequency of the properties of material, pasting layer, processing error, and the sizes of FEM net grids.
