The history of science and technology.

PDS-FEM [2], a three dimensional fracture method, is efficiency to calculate the crack paths, especially for the branch or bifurcation cases usually observed in brittle materials.
The current version of PDS-FEM can only carry out the fracture analysis of the elastic materials.
However, most of the construction materials show nonlinear characteristics before collapse.

Introduction Today’s huge consumption of non-renewable materials such as petroleum-based polymers and abundance of natural-organic wastes have become an impetus to promote recycling and increase utilization of natural-organic wastes in efforts to protect the environment.
Application of all sorts of natural-organic materials such as agro-waste natural fibers to reduce consumptions of petroleum-based polymers if not to eliminate is an alternative to fight global environment issues such as global warming and loss of biodiversity.
These natural-organic materials such as natural fibers are a suitable option for this purpose due to their properties such as biodegradable, less abrasive to machine parts, low density, acceptable specific strength, low cost, and light weight (1-5).
This plant was selected not only due to its positive attributes like other renewable organic-natural materials but also due to their increasing cultivation area in Malaysia for cosmetic and pharmaceutical industries and hence their wastes.

Morse, Blot and Brown (1940) studied about sound absorption of porous material [2].
Furthermore, Mechel and Vér (1992) stated that sound pressure brought about the sound; if the sound waves touch sound absorption materials during its delivery, the air molecule would dangle in the voids inside the material; energy would be worn off with the abrasion [4].
The material was close to rigid wall, the sound absorption would decrease.

In recent years, micromachining technologies have been widely developed to achieve 3D features in many materials that show more potential to being applied to engineering materials in the micro-fabrication domain [1-2].
The high accuracy and quality of products are achieved by ultra-precision machining technology, which are the trend of modern manufacture science and engineering and the base of modern science and high-tech[6-7].
The material of micro cutter is tungsten carbide.
It was easy for the removal of the material at this situation.
