Modeling and analysis of a prosthetic foot: A numerical simulation case study

Mar 7, 2024

Journal: Bio-Medical Materials and Engineering 35 (2024) 401–414 (401–414 DOI 10.3233/BME-240052)

Publisher: co-other

DOI: ineering 35 (2024) 401–414 DOI 10.3233/BME-240052

BACKGROUND: The prosthetic foot is an essential component of the prosthetic limb used by people who suffer from amputation. The prosthetic foot or limb is expensive in developing countries and cannot be used by most people with special needs. OBJECTIVE:Inthisstudy,anuncomplicated prosthetic foot is designed that can be manufactured at low costs using 3D printer technology and can be provid...
Designing and manufacturing a flexible heel of a printed prosthetic foot for rehabilitation

Feb 1, 2024

Journal: International Review of Applied Sciences and Engineering DOI: 10.1556/1848.2024.00930 (DOI: 10.1556/1848.2024.00930)

The prosthetic feet available in the market are characterized by high costs and are made of carbon fiber materials, fiberglass, or silicone-coated wood. This study aims to design and manufacture a prosthetic foot to enhance biomechanical performance and user comfort and mimic the natural movement of the human foot; the foot will be designed and manufactured from low-cost materials, namely ca...
Effect of Rotational Speed for Friction Stir Welding/Processing on the Mechanical Properties and Microstructure of 5083-O Aluminum Alloy

Feb 4, 2023

Journal: Proceeding of the 1st International Conference on Manufacturing Engineering Technology (IConMET 2021) (IConMET 2021) ((IConMET 2021))

Publisher: co-other

DOI: AIP Conference Proceedings

Abstract. This study looked into the effects of rotational speed on the mechanical and microstructural properties of 5083-O aluminum alloy welded using friction stir welding (FSW) and processing (FSP). 750, 1250, and 1750 rpm rotation speeds, and a steady travel speed of 50 mm/min. The welding and processing joints' tensile strength properties, microhardness, and microstructure were investig...
The Effect of Heat Treatment Conditions on the Mechanical Behavior of Ni-Ti Shape Memory Alloys

Oct 1, 2020

Journal: IOP Conference Series: Materials Science and Engineering 671 (3rd International Conference on Engineering)

Publisher: Asmaa Muneam Abdullah

DOI: 10.1088/1757-899X/671/1/012154

Ni-Ti shape memory alloy (SMA), and its alloys have been widely used for medical, mechanical and electrical applications. In this study, a (Nitinol) Ni-Ti alloy medical plate was prepared and cut using a wire cut machine. Eight samples were heat treated at 800°C and used for heating samples for 30 min and 60 min at this temperature, then cooled in four media: furnace, water, air, and ice bath. Mic...
Mechanical Properties Of AA 6061-T6 Aluminum Alloy Friction Stir Welds

Jan 5, 2015

Journal: Journal of Engineering 21 (06)

Publisher: Asmaa Muneam Abdullah

DOI: https://doi.org/10.31026/j.eng.2015.06.04

The different parameters on mechanical and microstructural properties of aluminium alloy 6061-T6 Friction stir-welded (FSW) joints were investigated in the present study. Different welded specimens were produced by employing variable rotating speeds and welding speeds. Tensile strength of the produced joints was tested at room temperature and the the efficiency was assessed, it wa...
An experimental investigation on fatigue properties of AA3003-H14 aluminum alloy friction stir welds

Jan 12, 2011

Journal: Journal of Engineering 17 (06)

Publisher: Dr.Ayad M. Takhakh, Asmaa Muneam Abdullah

DOI: https://doi.org/10.31026/j.eng.2011.06.07

AA3003-H14 aluminum alloy plates were welded by friction stir welding and TIG welding. Fatigue properties of the welded joints were evaluated based on the superior tensile properties for FSW at 1500 rpm rotational speed and 80 mm/min welding speed. However, there is not much information available on effect of welding parameters with evolution of fatigue life of friction stir welds. The present...
