Academic Projects

  • GRCop-84 Powder Development for Selective Laser Melting, Group Research Project | 03/2019 – 05/2019
      Investigated the feasibility of producing GRCop-84 structures on the EOS M270, a laser-based powder-bed fusion machine using a design of experiments coupled with metallography and optical characterization techniques to establish an optimal parameter set that produced nearly 99% dense parts.

  • Digital Twin for an Injection Molding system, Group Research Project | 04/2019
      Proposed a dynamic digital twin for injection molding utilized by a hypothetical multinational company to produce plastic gears. Used Solidworks Plastics package, Ubidots, Raspbian to demonstrate machine/simulation data acquisition, flow and optimization & addressed issues related to economic/geographical differences within overseas production facilities.

  • Direct metal investment casting using liquid resin stereolithography, Group Project | 11/2018
      Successfully fabricated zinc rings through direct-metal investment casting by using a master pattern 3D-printed via the liquid-resin stereolithography (SLA) process with castable resin on the Formlabs Form 2 printer.

  • Metal Foams: Product Design and Conceptualization, Individual Course Project | 04/2018 – 05/2018
      Ideated and presented a concept design to incorporate metallic foams in a Steering Upright structure; built on the design hypothesis by carrying out stress analysis, modal analysis using Solidworks and implementing vibration damping management and mass-cost-function balance in accordance with Ashby’s design guide.

  • Piezoelectric Ultrasonic motors in Photography, Individual Course Project | 04/2018 – 05/2018
      Conducted research on the design function and constitutive principles of piezoelectric ultrasonic motors in the context of the autofocus system used in digital cameras; used MSC Mentat analysis to perform modal and harmonic analysis of the stator component in a traveling wave motor.

  • Structural analysis of a defined composite I-beam structure using ANSYS, Group Project | 04/2018
      Executed a simulation-based design substantiation of three-point loading on a composite I-beam with specific load carrying capacity and failure constraints using ANSYS Composite Prepost; including fiber/matrix selection, orientation and layup sequence, maximum failure load prediction and a qualitative manufacturability assessment.

  • Programming a non-linear FEM incremental approach for a Belleville washer, Individual Course Project | 11/2017
      Coded a MATLAB script to model and approximate the non-linear load-deflection behavior in a Belleville washer as a series of small incremental linear problems using the finite element method, and critiqued the spring flat-out load results with classical solutions, analytical approaches and the influence of geometric variables.
