| Abstract In this paper the finite element analysiswas achieved on the above-knee prosthesis to investigate a picture of stress distribution in the socket.Previous works on the prostheses used the symmetry approximationinshape modeling and most of them are all about static loading.The analysisand shape modeling in this work were achieved in high accuracy with theaid of ANSYS 12.1 package software capabilities. Ofthis study, stressanalysis was achieved under dynamic loading at the three main gait cycle;soon after heel strike, foot flat and just before tow off as traditional stagesused in researches. This work lies on the dynamic loading calculated withthe ground reaction forces, dynamic forces, and moments as well as theangular and linear acceleration of foot up to the thigh during the three maingaitcycle. The stress distribution was achieved and it is imported to note that themaximum stress induced in the socket are at the upper brim whereas mostparts of the socket are consi-dered as a low stress region.
