Structural AnalysisLinear Static:
The most basic of all finite element analysis, I have significant experience modeling linear static analysis with NX Nastran via NX Simcenter and FEMAP, as well as modeling through ABAQUS. Much of my linear static analysis experience comes from performing detailed trade studies at the component level to determine optimal design parameters. I also have experience running linear static analyses on large scale models as mentioned below. Large Models: Over the course of three analysis internships, I have gained a sizeable amount of experience developing, maintaining and modifying large scale models encompassing hundreds of individual components. In this time I have created finite element models (FEM) for two separate satellite actuators, the entire PROVE Lab Endurance Car, as well as implemented many modifications to the Northrop Grumman NGP OPIR spacecraft FEM. I've performed a variety of analysis on these models, ranging from linear static, modal, and thermal analysis. Nonlinear Static: My mechanical engineering master’s thesis is in advanced nonlinear analysis of composite corrugated structures. Through this thesis I have gained experience in a variety of nonlinear metallic and composite simulations using NX Nastran via NX Simcenter and FEMAP. This analysis includes material plasticity, large deformations, large strains, contact analysis and progressive composite ply failure. In terms of simulations, I've performed linear and non-linear buckling, and basic, multistep and advanced nonlinear analysis types. |

Aerodynamic Analysis (Endurance Car)As part of my role as Chief Engineer on PROVE Lab's Endurance Car, I oversaw the detailed aerodynamic design and analysis of the vehicle's aeroshell. Working with a team of three other students, we ran Computational Fluid Dynamics (CFD) simulations through STAR CCM+ to determine the impact of various design changes. I primarily post processed the analysis results and drew conclusions on future design changes, while my team focused on the actual simulations. Through these efforts and many iterations, my team and I reduced the aerodynamic drag by over 40% from conceptual designs to achieve a CD of 0.12 and CDA of 0.23 m^2 (or 35 N of drag at 35 mph!).

Thermal AnalysisI have experience running thermal analysis simulations via a Computational Heat Transfer graduate course I took during my mechanical engineering master’s degree. Through this course I have a concrete background in finite element, finite volume, and finite difference analysis methods. I also have some experience solving forced convection analysis problems using ANSYS FLUENT for the simulation solver. In addition to this detailed thermal analysis, I also have experience in full thermal system design: I analyzed an office building’s thermal loads along with the financial costs of various heating methods.

Vibrations AnalysisFinally I have experience in vibrations analysis in free and forced vibration for multi degree of freedom systems and rotor dynamics. For rotor dynamics, I have experience analyzing shaft natural frequencies, orbits, shaft whirl and whip. I also have experience in gear box analysis in determining gear mesh frequencies and vibrations due to cracked teeth. Finally I have experience analyzing hydraulic bearings and their impact on muli-rotor systems. In terms of finite element modeling, I have performed modal analysis on a variety of structures to find natural frequencies and to find how best to stiffen or relax a design.
