Based on this property, many NN-based approaches have been developed to model the welding processes so that the system welding performance such as the convergence materials out gas and robustness to reduce air bubble number can be improved[2].a back-propagation NN for a shielded metal arc welding process used to establish the relationships between the process parameters and weld bead geometric parameters is presented in [3].he training algorithms for WNN typically converge in a smaller number of iterations than the conventional NNs [4]Thus, WNN has been proved to be better than the other neural networks in that the structure can provide more potential to enrich the mapping relationship between inputs and outputs [5].which are utilized to up-date the adjustable parameters of WNN controller on-line for further assuring system stability and online-taining a fast convergence.

a) The first model b) The second model c) The third model Fig. 2 Geometric drawing of models Finite Element Model The models are the elastic-plastic material completely, and their yield criterions are the Von Mises yield criterion.
This is due to the weld’s carrying capacity is weaker than the main material, and the weld at the upper and lower column connections is yield prematurely.
The third joint, failure surface is happened out of haunched slab (similar to the plastic hinge under the cyclic loading) and there first reach the ultimate bearing capacity of the material, to being a motor component.

In this way, Al concentrations in the range ~ 1-3.10 20 at.cm-3 have been reached and, both, Raman and TEM characterizations show that no foreign polytype or other material inclusion is formed.
The Al and Si sources used for the melt are, respectively, 4N material and pieces of Si wafers with electronic grade.

Such an assembly generates a nontrivial fiber bundle of material manifold.
We introduce material manifold as a fibre bundle of a smooth three-dimensional manifold.
Note that material manifold is a bundle and each its fiber is associated with a material surface strained before its adhesion to a body.
Thus, at each point of the material manifold tensor field is defined.

Therefore, these PE/TiO2 composites with such mechanical properties and bioactivity are considered to be useful as bone-repairing materials.
Introduction Recently, many kinds of bioactive materials have been developed [1,2].
Most of them are ceramics and metallic materials.
Since materials which do not break off but deform to some extent and absorb the fracture energy even under highly loaded condition are desirable for bone substitutes, this composites are useful as bone-repairing materials.
These composites are considered to be useful as bone-repairing materials.
