Introduction During the thermoelastic vibration process two types of stresses appear in a plate: elastic, caused by bending, and thermal stresses, which causes the material to expand.
(4) The constants R1–R3 depend on elastic properties of material and are given in [6].

The study found that timber and metal were highly recycled waste materials at both apartments.
Only four types of C&D waste focused such as metal, concrete, packaging materials and timber.
The recycling practices for packaging materials increases but drops in February (0.33m3).
The highly recycling materials is metal followed by timber, concrete and packaging material.

Composite materials have superior properties than those of the individual components when used alone depending on the type of materials being combined [3].
The concept behind composite materials is the combination of two or more materials in creating a new engineered material [4].
The classification of composite materials is based on the binder material, which binds or holds the filler materials, usually a polymer matrix, and the filler material, usually the fibers, sheets, fragments, particles, or whiskers of natural or synthetic material [1].

While the internal pressure is low, axial load takes leading roles and prompts tube materials flow in the direction of branch tube that also helps to alleviate the over reduction of wall thickness.
Another is that it may result in great friction resistance between mold and tube, which will hinder the materials into branch.
