and Coarse-grained Molecular Modeling of Chondroitin Sulfate Conformation, Titration, and Osmotic Pressure by Mark Bathe Bachelor of Science, Mechanical Engineering, 1998 Master of Science, Mechanical Engineering, 2000 Massachusetts Institute of Technology Cambridge, MA Submitted to the Department of Mechanical Engineering in partial fulfillment of the requirements for the degree of Doctor of P...

The method of modeling is the key technology for digital mockup (DMU). Based upon the developing for mechanical product DMU, the theory, method and approach for virtual environment (VE) and virtual object (VO) were studied. This paper has expounded the design goal and architecture of DMU system, analyzed the method of DMU application, and researched the general process of physics modeling and b...

Bone is able to react to changing mechanical demands by adapting its internal microstructure through bone forming and resorbing cells. This process is called bone modeling and remodeling. It is evident that changes in mechanical demands at the organ level must be interpreted at the tissue level where bone (re)modeling takes place. Although assumed for a long time, the relationship between the l...

this work is an attempt towards employing ductile damage criterion and finite elementsimulations for prediction of fracture initiation and evolution in deep drawing of copper/stainlesssteel clad sheets. the material mechanical properties and ductile damage parameters weredetermined through standard and notched tensile tests. the effect of some important processparameters on damage evolution wer...

Understanding of mechanical behaviors of the human body is a challenge to take appropriate medical decisions (e.g. patient's diagnosis or treatment). To achieve this objective, two modeling approaches were studied and confronted in order to highlight the benefits and limitations of each approach to clinical problems. The biomechanical model is including anatomical geometries, anthropometrical d...
