CAREER EPISODE 1
I) Introduction:
[CE 1.1]
The project that has been highlighted in the aforesaid career episode is the optimization of the lap shear strength during the bonding of those materials which are dissimilar. I performed the project tasks during the fulfilment of my Master’s of Engineering degree from Deakin University. The activities on this work were initiated by month, year and completed by month, year.
II) Background:
[CE 1.2]
The main aim is the optimization of the lap shear strength, which is adhesively bonded through the selection of the relevant parameters that are fit. The objectives of this project were to accomplish the relevant tasks by enhancing lap shear strength through different parameters.
[CE 1.3]
The parameters considered to attain the requisite goal included an adhesive thickness of 0.5 to 1mm, a surface roughness range of 0.2 to 0.8 micrometres, and a surface energy that favoured adhesion to the incorporated adhesive. The project outcomes were then treated as deliverables based on the parameters used. This project has been implemented to determine the maximum lap-shear strength, which can be incorporated into the design of the Deakin solar car.
[CE 1.4]
The tasks that were conducted were the following:
- Designed and manufactured the plastic material
- Designed the metal sample
- Prepared the surface by pre-treating the steel sample
- Pre-treated the surface of the plastic by sanding the relevant surface

CAREER EPISODE 2
I) Introduction:
[CE 2.1]
This career episode would comprehensively elucidate the Bachelor’s Degree project. The project is entitled ‘Optimisation of the Friction Stir Welding Parameters of Copper (C-1000) and Aluminium (AA-6082) using Grey Relational Analysis. I completed this project to fulfil my B. tech degree requirement.
I studied at the GITAM Institute of Technology. It was started in Month/Year and completed in Month/Year. It was based in City/country.
II) Background:
[CE 2.2]
This project will present the parameters optimization by considering the numerous performance characteristics of Friction Stir Welding, and this would be done by conducting grey relational analysis (GRA). To evaluate the machining effects, two performance characteristics were chosen for this project: Ultimate Tensile Strength and Hardness.
The project was carried out in two stages. In the first stage, we studied the parameters closely correlated with the chosen performance characteristics, i.e., Total Feed Rate, Axial Force, and Total Rotation Speed. Then, experiments were conducted first based on the accurate LA 09. After this, the experimental results obtained from performance indicators are introduced for calculating the grades and coefficient in accordance with GRA.
Further, in the second stage of the project, the parameters of the optimised process that simultaneously lead to higher Hardness and Ultimate Tensile Strength will be verified through a confirmation experiment. In the project’s first stage, the experimental procedure involved selecting appropriate materials, specimen sizes, tools, and FSW components, and then performing the welding. Moreover, microstructural analysis was also conducted for the specimen.
[CE 2.3]
The following Duties were assigned to me:
- Performed a literature review and studied numerous books to gather maximum knowledge before starting the project.
- Selected adequate materials such as aluminium alloy 6082 and copper C-11000 material.
- Implemented the friction stir welding process and developed the components of the FSW equipment.
- Carried out the microstructural analysis for relevant specimens and samples.
- Performed the project tasks by obeying the international standards.
- Communicated with the supervisor daily and developed the final report.
CAREER EPISODE 3
I) Introduction:
[CE 3.1]
The aforesaid career episode eloquently illustrates the details of my assignment project. The project is titled “Displacement and Vibration Analysis of a Wire under Various Conditions.” The time assigned to complete the project was Month/Year. I started working on the project in Month/Year and finished it in Month/Year.
II) Background:
[CE 3.2]
Over the past few years, multiple techniques and strategies have been developed to study the structures and the effects of several parameters on them. By using the developed methods and techniques, we can precisely measure all factors that significantly affect the structures. Thus, this project was designed to analyze the vibrational frequency and displacement of a wire piece accurately.
The project’s main aim was to determine the Young’s modulus of the wire by fixing one end as a cantilever. Then, the wire will allow bending in a random shape, and one side was clamped again as a cantilever beam. This experimental setup was created to observe the wire’s deflection and to examine the frequency of the first mode of vibration, both with the wire free and with a load applied at the free end.
[CE 3.3]
The following Tasks were assigned to me:
- Researched and developed a better understanding of vibrational and displacement analysis.
- Examined the vibration and displacement in the wire by applying three methods such as Analytical, Experimental, and using Abaqus software.
- Determined Young’s modulus of the given wire by performing calculations and making a few assumptions.
- Developed the model of bent wire in the Abaqus software and determined the bent wire’s displacement and vibrational frequency.
- I explained the results to the supervisor and made the final report.
- Ensured all the project activities were conducted according to the Internal Standards. Get complimentary CDR samples through AustraliaCDRHelp.Com.
