Introduction Left-hand materials (LHM) or negative refractive medium is a new type of artificial electromagnetic materials developed in recent years [1].
Because of the different dielectric constants and the permeability of left-hand materials(LHM) are related to the parameters of S11 and S21.

The traditional robots use rigid materials for structural elements and actuators, which limit their ability to adapt to the surrounding environment.
Different hyper elastic rubber materials were attempted in the above researches and finite element analysis (FEA) was also done.
The non-linear material model is the one need to be used for characterizing hyper elastic materials.
Non-linear Material model The hyper elastic materials have large strains and must be characterized by finite deformation theory.

HPW/CdS composite materials were prepared by impregnation method.
By comparing the IR spectra of composite materials with simplex sample of HPW and CdS.
The composite materials show the better photocatalytic activity than others.
The recycling studies of composite materials are still going on.

The first condition to respect is the choice of the materials "Real" and the "Model".
The law of flow"s material formulates that as for real materials, simulation materials behave the same when constraints overcome a certain threshold.
The materials used as follows: representing AA2024T3 is beige plasticine (modeling clay) and red plasticine for the copper sheet[9,10].
The final result will be the creation of a model of FSW for different materials with different kind of joining 5_References [1] NANDAN (R)-DEBROY (T)-BHADESHIA (H K D H) - Recent advances in Friction Stir Welding-Process,Weldment, Structure and properties - Progress in Materials Science 53 PP 980-1023 (2008) [2] BASTIER (A), Modélisation du soudage d'alliages d'aluminium par friction et malaxage, Thèse de doctorat de l'Ecole Polytechnique, décembre (2006) [3] GLUKHMAN (A.A.). - Introduction to the theory of similarity.
