Problem Statement
After an accident, a human was injured with bone fracture at the ribs though CT scan. In order to find out the cause of this injury, Accurate human bone model was modelled and the impact of the external object to the ribs are accurately simulated using Finite Element Analysis (FEA) method, by Abaqus.
Digital Conversion and Matching
Before running the simulation, an accurate 3D model was converted from CT Scan data and the physical ribs model of the victim (with fracture bone) was produced using 3D printing method. The physical ribs model was used to determine the possible orientation and position that might cause the particular injury.
Impact Simulation
From the digital matching, possible accident scenarios were obtained and set up in Abaqus. The material properties of the rib were obtained from the published research paper. Through FEA simulation, the stress distribution, deformation and fracture on the ribs can be obtained. The results matched well with the outcome of the accident.
Takeaway
After matching the results from FEA simulation with the outcome of the accident, one can predict the possible causes of the accident accurately.
Frequently Asked Questions
It all depends on the inputs and boundary condition that is defined in the simulation. Through accurate on-site measurements and material properties definition, accurate results can be obtained which resemble the simulation to outcome of the accident.
The results from FEA such as stress distribution, fracture location, deformation strain, impact direction & kinetic energy, etc. of the bones can help in predicting the cause of an accident.
