•Designed three types of truss members in SolidWorks that gave satisfactory results in theoretical static finite element analysis
•3D printed the truss members of ABS in horizontal and vertical fiber orientations and performed compression testing to check for the maximum load capacities
•Compared the theoretical results for the load at 1% strain per unit mass of the truss structures for varying mesh size with the experimental results

•Discussed how conventional NDE methods such as ultrasonic inspection and acoustic emission are suitable for a wide range of materials
•Illustrated how advanced NDE methods like Vibrothermography, Computed Tomography, Thermosonic Testing, and Laser Ultrasonic Testing help in detecting surface and subsurface defects in the landing gear, fan blade, and turbine blade of aerospace structures

Project Overview: The purpose of this project is to develop a structurally compact and low cost desktop filament extruder for desktop 3D printers as a way for individuals to take part in the growing 3D printing trend. Within that scope, the project aims to combine an extruder unit together with a winding system in the same device so that the resulting filament is effectively wound to a filament spool.

Project Overview: The goal of this project was to create a shipping container to transport a specialized control unit for an unmanned underwater vehicle (UUV) from their research facility to their field sites. If the inertial loading on the system exceeds 8N the control unit can be damaged, leading to sending the vehicle back for further testing and analysis which costs lots of money. The purpose of this project was to create a warning system to notify the workers unloading the sensor of… Show more

Project Overview: The goal of this project was to create a shipping container to transport a specialized control unit for an unmanned underwater vehicle (UUV) from their research facility to their field sites. If the inertial loading on the system exceeds 8N the control unit can be damaged, leading to sending the vehicle back for further testing and analysis which costs lots of money. The purpose of this project was to create a warning system to notify the workers unloading the sensor of whether or not the package has been compromised of that maximum inertial loading of 8N. (Under Dr. Jason Armstrong)

Role: This position along with another member of the group selected a number of components from the ones made available to us to set up two different systems to serve our experimental purpose of developing a warning system using one primary setup and the other as a backup. Our first approach was to create an Arduino system where an accelerometer was used as the sensor. Our second approach was to use a load cell to detect the force from the load hanging from it. After the two setups were done, we discussed the setups with the remaining two members to improve the design for better results. Show less
