The material parameter is set in accord with Q345.
Since the stresses of the tube are below the yield stress of the material, the analysis is conducted in linear scope.
The stress nephogram in Fig.8 indicates that the biggest Von Misses stress of the joint is 38.7MPa which is far below the yield stress of the material.

The molten materials were quenched to room temperature in stainless stain mould and subsequently annealed at 450 °C.
In the amorphous materials, the optical band gap energy is closely similar to the energy gap between valence and conduction bands.
The acknowledgment also contributes to the Center of Excellence in Glass Technology and Materials Science, NPRU for the facilities.

These materials are encased inside a stainless steel tube to ensure the durability.
In previous experiments, we attempted to connect all materials in one step.
The surfaces of the materials were connected under observation through a microscope.
Second step is adhering coupled materials and optical fibers.
We placed and adhered these materials with observing the microscope.
