Computer Aided Design And Finite Element Analysis
There is a special facility in the Mechanical Engineering department in the form of a computer design and simulation studio for the subjects of CAD, FEA, biomechanics and biomaterials.
Current projects in these fields are:
- Finite element analysis of temporomandibular joint of a pig
Introduction: This project is in collaboration with the Physical Therapy department at Ohio University. In this project, we have developed the first finite element model of a pig's TMJ, with the aim of getting the stress/strain patterns at the disc and the surrounding bone.
Significance: The TMJ disorders include pain dysfunction syndrome, internal disarrangement, arthritis etc. Some researchers say that almost 25% of the world population suffers from these disorders and only one sixth of those get the proper treatment. This study will help in developing a better understanding of the stress patterns in the joint and thus will help in analyzing the cause of the disorder.
Methods: There are five basic steps in our methodology. They are: geometry, mesh, material, loads and boundary conditions. For the geometry we used CT images, Amira (Visage Imaging, USA-Germany) and MSC.Marc. Meshing was done using MSC.Marc. Materials, loads and boundary conditions are the current areas in which we are working.
Presently ME grad Sarang Dalne is working on this project under the guidance of Dr. John R. Cotton.
- Modeling of a hip joint
- Cellular deformation simulation
- Bone remodeling simulation
Presently Dr. John Cotton is working in this area.
