Advanced Finite Element Method for Solids
ME 65100/ 3 Cr.
This course is designed to teach students advanced non-linear finite element techniques for solid mechanics stress and heat transfer analysis. Those include techniques for modeling: 2D/3D continua; beams; plates; large rotations; geometric non-linearity; material non-linearity; material plasticity; heat transfer; modeling thermo-mechanical systems; frequency domain solutions; quasi-static solutions; time domain solutions; modeling of frictional contact; and modeling rigid-bodies. Applications of the modeling techniques taught in this course will be introduced. Those include: static and dynamic stress-analysis of mechanical components (such as gears, cams, chains and belts) with material and geometric non-linearity; modal analysis of mechanical components; metal forming and crashworthiness analysis.
