Abstract
People with special needs who wear prosthesis lower limb which is artificial device using to replace for missing body part. This work involved two major parts, the first part beginning with manufacturing of the prosthetic socket from composite material (3pyrlon,3carbon,3pyrlon), the patient case study is man with (85kg, 23 year, suffer from amputation below the knee of his right limb, the amputation occurs due to trauma accident). The GRF test is needed to determine the ground reaction force subjected on the patient foot. Also, F-Socket test is done to measure the interface pressure between the below knee prosthetic socket and the residual lower limb using pressure sensor. The second type of tests include mechanical test which employed on the specimen manufacturing from the same material of prosthetic socket. This test including tensile test to finding the modules of elasticity (1.109 GPa), yield stress (34 MPa), and ultimate stress (38 MPa).The last part of this work is focus on the simulation of the BK prosthesis, to calculate the equivalent (Von-Mises) stresses, and deflections by using ANSYS software (14.5).The results show that the maximum equivalent Von- Mises stress is equal to (18.5 e7 Pa), also the maximum deflection equal (0.00604 mm).
