The rigid visco-plastic FEM is the main numerical simulation method in the metal bulk forming and its basic equation is based on the Euler coordinate system.The basic assumption of the rigid visco-plastic flow theory is[4,5]: ignoring the elastic deformation of the material and the quality stress and the inertia force; the materials in even quality and having the same character of their directions; the volume of the material not changing; the materials abiding by the Mises yield criterion and strengthening at the same direction; the rigid-plastic material changing only on strain hardening while the rigid visco-plastic changing on both the strain hardening and strain-rate hardening simultaneously.

Experimental LiNi1/3Mn1/3Co1/3O2 were synthesised using solid state synthesis route at high temperature by mixing metal acetate salts (Aldrich) as the starting materials.
Results are comparable in literatures [1, 4] for materials that are prepared using conventional solid state synthesis route.

The use of natural fibers in this process is inexpensive and such materials can be referenced as biocomposites, saving the primary raw material.
Introduction Composite materials can be characterized as systems that take advantage of its partial phases [1-2].
The most common type of composite materials is primarily long-fiber composites with arranged fibers.
Sisal fibers are used, for example, for increasing the strength of polymeric materials.
