Alumni

 

Damon Burnett

Degree Earned: M.S. Mechanical Engineering, Rensselaer Polytechnic Institute, 2002

Project: My research focused on Dynamic Strain Aging (DSA) in aluminum-magnesium alloys. DSA is a temperature dependent phenomenon caused by the interactions between solute atoms and mobile dislocations, and while these interactions strengthen the material, they also have an adverse affect on formability. I developed and implemented a grain scale constitutive model of this phenomenon. The goal then is to better understand how to increase the formability of an aluminum-magnesium alloy for a particular temperature.

Binoj Ramesh

Degree Earned: Ph.D. Mechanical Engineering, Rensselaer Polytechnic Institute, 2003

Project: This research involved developing more efficient finite element models for modeling forming processes and using these models for the determination of optimal parameters in metal forming processes. A stabilized finite element formulation was developed for efficient modeling of large deformation processes. This was coupled with a genetic algorithm for determining optimal processing conditions. Examples of design criteria that have to be satisfied include obtaining desired geometry, uniform microstucture in the workpiece and controlling the strain rates and temperature in the workpiece.

Ming-ting Wu

Degree Earned: M.S. Mechanical Engineering, Rensselaer Polytechnic Institute, 1997

Project: Modeling thermal stresses and defects in thin metallic films

 

Chia-Ju Yang

Degree Earned: Ph.D. Mechanical Engineering, Rensselaer Polytechnic Institute, 2004

Project: This research involved modeling electromigration and stress driven diffusion in thin metallic film. Electromigration and stress driven diffusion in electronic interconnects is a major cause of failure in integrated circuits. It can cause voids to form in the interconnect lines, which leads to open circuit failure. The object is to solve for the stress field using the diffusion equation combined with mechanics of crystals equations using the finite element method.
