Simulation of Femur Bone Fracture in Car Accident using CT Scan Data and Finite Element Analysis
Fracture of femur bones in car accident is common. In the present work, the fracture of femur bone was modeled as a failure under three-point bending. The CT scan data was converted into 3D solid modeling using Mimics software. The finite element analysis (FEA) was carried out using ANSYS software. The FEA results were in good agreement with the experiment results.
متن کاملA comparison of finite element and atomistic modelling of fracture
Are the cohesive laws of interfaces sufficient for modelling fracture in polycrystals using the cohesive zone model? We examine this question by comparing a fully atomistic simulation of a silicon polycrystal to a finite element simulation with a similar overall geometry. The cohesive laws used in the finite element simulation are measured atomistically. We describe in detail how to convert the...
متن کاملFlexural Strengthening of Deficient Reinforced Concrete Beams with Post-Tensioned Carbon Composites using Finite Element Modelling
The application of external post-tensioned steel bars as an effective way to strengthen an existing bridge has been so far used in many different countries. In recent decades, however, they have been replaced by bars made from Carbon Fiber Reinforced Polymer (CFRP), as a material with high tensile strength and corrosion resistance, to address several concerns with steel bars such as their appli...
متن کاملFinite element analysis of human femur bone
An effort is made to analyse the stresses experienced by the human femur. In order to achieve these results a CAD model was developed by using the 3-D scanning of generic human femur for an individual of 70 kg weight (approx. averaged adult weight). The marrow cavity has been approximated as a hollow cylinder. The FEM model was built using solid tetrahedral element (20-noded 186 structural soli...
متن کاملAn investigation of tensile strength of Ti6Al4V titanium screw inside femur bone using finite element and experimental tests
The geometric optimization of orthopedic screws can considerably increase their orthopedic efficiency. Due to the high geometric parameters of orthopedic screws, a finite element simulation is an effective tool for analyzing and forecasting the effect of the parameters on the load-bearing capacity of different types of screws and bones. Thus, in the present study, the tensile strength of a typi...
