Mechanical Investigation on the Foot Orthosis of Carbon Fiber (CF) Based on the Dynamic Loads: A Finite Element Analysis
Year: 2025
Type: article
Abstract: In this comprehensive study, a sophisticated finite element analysis (FEA) methodology was employed to investigate the mechanical properties of a foot orthosis meticulously crafted from carbon fiber (CF). The primary focus of this research centers around the dynamic loads exerted on the orthosis during various activities. Utilizing a static structural analysis tool, we meticulously configured both the pre-analysis and post-analysis phases of the simulation process, which specifically addressed the behavior of the fiber optic (FO) within the carbon fiber material. A critical component of this investigation involved a convergence study based on a thorough deformation analysis, which allowed for an in-depth exploration of unique stress types that impact the orthosis. The range of stresses analyzed included not only von Mises stress but also various other typical stress categories relevant to the device's structural integrity. Furthermore, the research delved into the magnitude and implications of these stress levels, contributing to a comprehensive understanding of the orthosis's performance under load. To achieve a complete analysis of the current scenario, a detailed examination of the overall deformation of the orthosis was undertaken. Remarkably, the findings revealed that the maximum deformation experienced at the tip of the foot reached an incredibly minute measurement of just 0.001 millimeters. The crucial numerical findings for von Mises stress indicated a value of 19.1 MPa, providing valuable insights into the material's limitations. The simulation results highlighted that the concentration of stress primarily occurs in the regions of the foot located behind the heel, shedding light on potential areas for further optimization and design enhancement.
