Introduction Due to environmental impact persistent of non biodegradable materials is growing global concern, biodegradable composite are one of the key factors to become an acceptable alternative.
More generally, it seems accepted that applications of different materials developed will be suitable for certain areas, but general applications remain limited.
However, the oil products represent only 10% of the total biomass, which the remaining 90% consist of waste materials [3].

The behaviour of the annular plates under vibrations differs from mode to mode, with material, with cross section, crack location, crack depth, crack length and differs with materials.
In the present study the chosen materials were Aluminium, Inconel, Rene 77, Polycarbonate Plastic, Cast Iron, Grey Iron, Stainless Steel, Ceramic Matrix Composite and Nimonic 75.
Several sets of modal analysis has been conducted with varying boundary conditions, number of cracks and different materials.

For welding tools, the optimal materials, sizes and geometries were adapted to each pair of welding materials and for each a FSW technology was developed (Figure 3).
Evolution of FSW tool shoulder force on welding materials Exp.
Optical microscopy analyses revealed the participation of both materials in the welded joint, forming a nucleus in which the flow lines of the materials are observed (Figure 9).

Resistance of materials.

Materials and Methods Li7La3ZrSnO12 were prepared by mixing raw materials using planetary ball-milling and followed by firing at 950 oC with intermittence grindings.
All raw materials were dried for an hour to remove moisture prior weight to obtain precise mol ratio in the mixing.
Then, the mixed raw materials were inserted into a jar and planetary ball-milled for 60 minutes at 600 rpm.
