COMPUTER MODELING AND CALCULATION OF HIP JOINT BY USING FINAL-ELEMENT ANALYSIS WITHIN ANSYS WORKBENCH

Abstract

The article describes a computer experiment for comparative biomechanical analysis of the hip joints, which examines one of the possible ways to restore the geometry of the hip joint according to computed tomography. To study the biomechanical factors leading to pathologies or their aggravation, the finite element method is used - a modern effective numerical method for solving complex problems. Computerized three-dimensional geometrically models of hip joints with various types of dysplasia, as well as a model after conservative treatment, were created. Building models was carried out using the program SolidWorks. The finite element calculation was performed in the ANSYS Workbench program. The stress-strain state in various model situations is determined.
