BRAIN AND CVS SIMULATION. FINAL REPORT

This report consists of three distinct parts. In Part I, a series of computer simulations using the Ward brain model (three dimensional finite elements), which employed two linear, elastic slightly compressible materials, was carried out with or without a small amount of slip. Another simulation using a simplified half cylindrical geometry to investigate further the effect of slip was performed. In Part II, a non-linear model is developed using finite element approach capable of large strain. The model was exercised for static loading on a flat sheet. The result was checked with published results by another method. The program was exercised to simulate gel-like material, and checked with the experimental results. In Part III, the CVS program was modified by adding a Lobdell Mechanical circuit to reflect the deformability. The model was tested for upper and lower torso with encouraging results. Finally, a brief literature survey was made on neck and femur deformability.
