Pro Tips for Choosing Your Topic

• Always prioritize primary sources like peer-reviewed journal articles from IEEE Xplore or ScienceDirect over general engineering blogs.
• Check the specific Harvard variation required by your university (e.g., Cite Them Right or Australian Government Style), as punctuation in engineering citations varies.
• Use technical standards (ISO, ASTM, IEEE) as authoritative sources for methodology sections to demonstrate professional awareness.
• When citing software or simulation tools like MATLAB or Ansys, include the version number and the developer in the reference list.
• Narrow your scope by focusing on a specific material grade or a specific mathematical model rather than a general engineering concept.
