The document details three engineering projects: a stress analysis of Boeing 787's door and window using ANSYS and MATLAB for SCF comparisons, a thermal analysis of Inconel 718 involving automated cutting based on temperature, and a design project addressing stiction during microstructure formation through a vacuum chamber. Each project includes visual representations and methodologies that were employed. The author contributed significantly in their role, including publication and collaborative efforts.

1. PROJECTS
1. Stress Analysis ofDoor and Window of Boeing 787 anisotropic Aircraft
This Project was my Dissertation during Masters of Engineering, I have published the paper in
International Journal of Engineering, Research and Technology Journal (IJERT). Model was
developed using Ansys and analysis was done using Structural Analysis of an Orthotropic
Material to find Stress Concentration Factor (SCF around the Door or Window and when both are
present in the vicinity. These were compared with the results obtained by analytical solution in
Matlab. Following are the results obtained,

2. Thermal Analysis ofInconel 718
I was part of a Group doing this project, where I was responsible to do the cutting
operation at the desired temperature,so after thermal analysis the critical temperature was
found it was to be cut or moulded. Following are the pictures,

4. An automated system was developed using a thermal sensor which would move the specimen
front and back when the temperature is varying in front of the lathe machine.
3. Removal ofStiction Problems during Microstructure formation:
When microstructure are formed, in the process the filaments gets together due to interconnecting
forces between them (Vander Val Forces). This is termed as Stiction simply,
The system was desgined to remove those forces. I was responsible to Desgin the Vacuum
Chamber of the System, Following are the pictures,
Above figure shows the CAD model of the vacuum chamber developed with dimensions
using AutoCAD.
Following is the experimental setup,
