Numerical Investigation on the Performance of Prosthetic Running Blades by Using Different Materials

Abstract

The amputation of a lower limb for humans is one of the most traumatic experiences, both physically and emotionally. Prosthetic running blades provide disabled persons with an opportunity to participate in sports and thus help to improve their psychological health. They also allow them to participate in activities that were previously unavailable to them due to financial constraints. In the current study, we looked at how different materials affected the functionality of prosthetic running blades. We investigated the static behavior of a prosthetic running blade using finite element modeling. Under various load circumstances, we conducted numerical simulation using a variety of materials, including titanium alloy (grade 5), carbon fiber, stainless steel (AISI 316), and aluminum alloy (2024 T4). We studied three major load conditions: rest (700 N), walking (1400 N), and running (2200 N). To understand the performance depending on the selection of materials, we evaluated total deformation, equivalent stress, and strain energy in the design of our experiment. The titanium alloy is more durable and has a higher tensile strength. The high cost of manufacture for titanium alloy, however, is a major deterrent to its use in running blades. It was noticed that the aluminum alloy (2024 T4) blade goes under much deformation as compared to titanium and carbon fiber-made running blades. Furthermore, carbon fibers offer excellent mechanical properties, which are essential for creating running blades. It has outstanding tensile properties. Additionally, the low density of carbon fiber has the added advantage of making running blades lighter.

Nanotechnology and Prosthetic Devices: Integrating Biomedicine and Materials Science for Enhanced Performance and Adaptability

“…A wide range of nanomaterials have found applications in prosthetic devices. Nanoparticles are particles at the nanoscale that can be engineered from various materials, such as metals, ceramics, and polymers (Goh et al, 2002;Campbell et al, 2012;Lindberg et al, 2018;Kadhim et al, 2019;Abbas et al, 2020;Abubakre et al, 2023;Siddiqui et al, 2023). These nanoparticles find applications in drug delivery systems, enabling targeted and controlled release of medications to alleviate pain, reduce inflammation, or promote tissue regeneration.…”

Assessment of a Carbon Fiber Prosthetic Running Blade for Enhanced Reliability

“…On the other hand, numerical modeling enables a comprehensive evaluation of the prosthetic running blade's reliability, including factors such as stress distribution, strain patterns, and energy absorption (19,22,28). Moreover, numerical modeling facilitates design optimization by exploring various parameters such as materials, geometries, and structural configurations.…”

Exploring Orthosis Designs for 3D Printing Applying the Finite Element Approach: Study of Different Materials and Loading Conditions

“…A biomechanical study using finite element (FE) analysis helps to examine the mechanical behavior of the designed orthoses under different loading and other boundary conditions for various materials. The FE technique offers tremendous time and cost savings for assistive devices such as orthoses (or splints), prosthetics, etc., that need to be modified and checked regularly for different materials and thicknesses (Kubasad et al, 2020;Siddiqui et al, 2023). FE analysis predicts the success and failure of the 3D model by studying the biomechanical properties, thus simulating realworld scenarios.…”
