BRACE SIMULATION FOR PATIENTS WITH SCOLIOSIS: BIOMECHANICAL COMPARISON WITH THREE DIFFERENT POLYMERIC MATERIALS

SEPTEMBER 2019 - VOL.15 | ORIGINAL ARTICLE
OBJECTIVES

The purpose of this research is to investigate injuries to the spinal cord and scoliosis and to review the most recent and common therapies. In particular, this study has been designed to simulate and compare braces composed of three different materials to determine the optimal material.

MATERIAL AND METHODS

Solidworks and Abaqus softwares have been used in this study. We simulated and redesigned a new type of brace (ART Brace) and compared it in three different materials (three types of polymer: Nylon 66 with 50% Mica, Nylon 66 with 30% Carbon and Nylon 6 with 30% Carbon).

RESULT

We examined stress and strain and the rate of displacement of the brace, and the best material was selected and evaluated for the desired brace. In these studies, Nylon 66 with 30% carbon has the highest stress and Nylon 66 with 50% Mica has the highest strain and displacement, while Nylon 66 with 50% Mica has the lowest stress and Nylon 66 with 30% carbon has the lowest strain and displacement.

CONCLUSION

According to conducted surveys on three different materials we concluded that the optimal brace should be made of Nylon 66 with 50% Mica as this performed better than the two other materials (Nylon 66 with 30% carbon). This is because the rate of stress is lower after loading.
