We needed to ensure that the implant could withstand the mechanical stresses it would encounter in the human body without failing or causing damage to surrounding tissues. I used finite element analysis to model the implant and simulate various loading conditions, such as walking and running.

By doing this, I was able to identify potential weak points in the design and make necessary adjustments before we moved on to prototyping. The FEA results were pivotal in optimizing the implant’s geometry and material properties, ultimately leading to a more robust and reliable final product. This not only saved time and resources but also contributed significantly to the project’s success, as our prototype met all the stringent testing criteria on the first try.”
