The combinatorial objects of the simulation model assembled by the CAD software was loaded using ANSYS Workbench software; the model material and the mechanical properties of the model were selected, and the model was subsequently gridded.
Assumptions for material parameters, force strength, and boundary settings are required during the simulation process.

They can absorb light in the near ultraviolet region of the spectrum and re-emit the light as violet-blue fluorescence, which raises the whiteness and brightness notably as the violet-blue fluorescence complements the yellowness and adds a bluish hue to the materials [1], as well as increases the intensity of the reflected light yet.
