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 provided to a wide range of amputees. The foot was designed using CAD software and analyzed using ANSES. METHODS: Carbon fiber material was chosen to be suitable for the manufacturing process using 3D printer technology. The selected material was tested in tensile and fatigue tests to determine its mechanical properties. The numerical analysis was carried out assuming the use of an artificial foot by a patient weighing 85 kg. RESULTS:Theresultsshowedthatthematerialproposedformanufacturinghasgoodmechanicalpropertiesforthisapplication. The results of the engineering analysis also showed that the model has successfully passed the design process and is reliable for use by amputees. CONCLUSION: The success model designed in this study in the numerical analysis process gives reliability to the use of this design to manufacture the prosthetic foot.

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 carbon fiber filaments, using 3D printer technology. The practical part consists of tensile, fatigue tests, and manufacturing the foot using a 3D printer. In this study, the ANSYS program will also analyze the designed model numerically to determine the stresses generated when applying the assumed body weight to the foot model. The results showed that the model is successful in terms of design and does not suffer any mechanical failure during use, in addition to the success of the selection of the material used in the manufacturing process due to its mechanical properties, where the yield stress value 5 36.4MPa, the ultimate stress value 5 58.39 Mpa and Young’s modulus 5 1.23GPa.

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 investigated and compared to the base alloy. The rotation of the sub-grains, which produces dynamic recrystallization in friction stir welding, causes fine grains to appear in the weld region. For friction stir processing (FSP), the rotation speed is increased to 94.7 percent of the base metal's ultimate tensile strength.

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. Micro-hardness and microstructure measurements were taken, as characterization techniques, to investigate the effect of cooling rate on mechanical properties. Micro-hardness results showed the HV is 316.36 HV at ice cooling rate for 800 °C and 60 min heating time, and 275.5 HV for 800 °C heating for 30 min and ice cooling media. The results show the correlation between cooling rate and properties of the alloy.

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 was 75% of the base metal at rotational speed 1500 rpm and weld speed 50 mm/min. Hardness of various zones of FSW welds are presented and analyzed by means of Brinell hardness number . Besides to theses tests the bending properties investigated and showed good results in some specimen and not in on other the maximum stress was 240 N/mm2 at rotational speed 1500 rpm and weld speed 50 mm/min , while the maximum stress at 1250 rpm and 75 mm/min 94 N/mm2 , hardness results showed lower values in heat affected and nugget zones than the base metal with improving of hardness at 1500 rpm, 75 mm/min .

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 study experimentally analyzed fatigue properties for base, FSW, and TIG welds of AA 3003-H14 aluminum alloy. Fatigue properties of FSW joints were slightly lower than the base metal and higher than TIG welding.
