“…1. The modulus of elasticity, yield strain, and ultimate stress of the materials utilized to manufacture prosthetic limb sockets were calculated using a computer-numerical control machine (CNC) to cut for each sample according to the American Society of Testing Materials ASTM D638(I) dimensions [34,35]. The samples were tooled as shown in Fig.…”

In this research, the use of natural materials like wool and cannabis as intermediate reinforcement for prosthetic limbs due to their comfort, affordability, and local availability was discussed. As part of this study on below-the-knee (BK) prosthetic sockets, two sets of samples were made using a vacuum method. These sets were made of natural fiber-reinforced polymer composites with lamination 80:20: group (Y) had 4 perlon, 1 wool 4 perlon, and group (G) had 4 perlon, 1 cannabis 4 perlon. The two groups were compared with a socket made of polypropylene. Tensile testing was used to determine the mechanical characteristics of the socket materials. The Y group has a yield stress of 17 MPs, an ultimate strength of 18.75 MPa, and an elastic modulus of 4.021 GPa, while for the G group, these values are 12.75 MPa, 18.84 MPa, and 4.076 GPa, respectively. The fatigue test was used to evaluate the failure characteristics of the socket. An F-socket was utilized to test the interface compression between both the limb and the socket. For the Tekscan sensor, the calculated pressure in the medial region is 350 K Pa, while it is 330 KPa in the posterior region. Solid Works software was used to draw a prosthetic socket for the numerical study. The failure safety agent for the composite material for group Y was 1.26. The finite element method (ANSYS Workbench 14.5) was used to look at the fatigue characteristics to detect the maximum stress, safety factor, and total deformation.

“…Finally, support the composite plate structure, as SSFF and CCFF plate supported, then input the mechanical properties of materials were calculated by experimental technique, [72][73][74][75][76], and then solve the considered case study to evaluate the composite plate's buckling behavior, with different nanomaterials effect. Then, compare the numerical results calculated with the experimental results, and the discrepancy between the results is evaluated [77][78][79][80][81][82][83][84][85][86][87][88][89][90][91][92].…”

Modifying buckling behavior of the composite structure has been investigated in the recent few years with different reinforcement fiber and powder materials and nanomaterials. It can be seen from previous studies that the addition of nanomaterials leads to a significant modification in the buckling behavior of structure by using a low mount of nanomaterials. In this work, reinforcement of composite materials using two types of nanomaterials together, SiO2 and Al2O3 nanomaterials, to modify the buckling behavior for plate structure is studied. Therefore, the investigation was done experimentally and numerically. The experimental work is performed by manufacturing composite plates with various weight fractions with the nanoeffect, and then their mechanical properties and buckling characterization were evaluated. The numerical work was done using the finite element method to estimate the plate structure’s buckling behavior with various nanomaterials effects. A comparison between the experimental and the numerical results for plate buckling behavior is expressed, showing that the discrepancy of the results was not more than 12.56%. Finally, the results showed that the buckling behavior for a reinforced plate was improved by 35% when two types of nanomaterials were used together.

The pylon is an essential part of lower limb prosthetics. It is usually made of titanium, aluminum, and steel. However, it is expensive and difficult to be available in developing countries, especially for children who suffer from amputation. Moreover, they constantly need new pylon pieces during close periods due to the growth and increase in the child's length.PurposeThis study aims to design an adjustable pylon that can change in length to suit the increase in the length of the healthy leg of the child without the need for a new pylon and reduce the economic cost.Design/methodology/approachIn this study, an adjustable pylon model was designed using the CAD software (Solid work) and work to manufacture the pylon from low-cost materials (carbon fiber filament) capable of bearing the amputee's weight, and manufacturing printed parts by using additive manufacturing technical (CREALITY CR20 3D printer).FindingsThe results showed that the pylon is successful in design and strength as it bears the patient's weight without any failure or buckling, and the proof that the maximum amount of stress generated is 27.8 MPa, which is far from the value of the yield stress.Originality/valueThe design of the adjustable pylon prototype offers good strength and ability to bear the patient weight, reducing the cost and time of manufacturing.
