Important Notes:

As a student of mechanical engineering looking to get good grades, it is essential to develop new ideas and experiment on existing mechanical engineering theories – i.e., to add value and interest to the topic of your research.

The field of mechanical engineering is vast and interrelated to so many other academic disciplines like  civil engineering ,  construction ,  law , and even  healthcare . That is why it is imperative to create a mechanical engineering dissertation topic that is particular, sound and actually solves a practical problem that may be rampant in the field.

We can’t stress how important it is to develop a logical research topic; it is the basis of your entire research. There are several significant downfalls to getting your topic wrong: your supervisor may not be interested in working on it, the topic has no academic creditability, the research may not make logical sense, and there is a possibility that the study is not viable.

This impacts your time and efforts in  writing your dissertation as you may end up in a cycle of rejection at the very initial stage of the dissertation. That is why we recommend reviewing existing research to develop a topic, taking advice from your supervisor, and even asking for help in this particular stage of your dissertation.

Keeping our advice in mind while developing a research topic will allow you to pick one of the best mechanical engineering dissertation topics that not only fulfill your requirement of writing a research paper but also add to the body of knowledge.

Therefore, it is recommended that when finalizing your dissertation topic, you read recently published literature in order to identify gaps in the research that you may help fill.

Remember- dissertation topics need to be unique, solve an identified problem, be logical, and can also be practically implemented. Take a look at some of our sample mechanical engineering dissertation topics to get an idea for your own dissertation.
