I am from metallurgical engineering background. I am doing PhD in mechanical engineering. I have an average of B+ in my undergrad advanced mathematics and programming courses. I have no past exposure to Non linear mechanics and Finite Element Analysis.
I am in the first semester of my PhD and I don't have the courses on Nonlinear mechanics and Finite element analysis being offered in my university for the next two years.
If I manage to self study the material from books and publish 2-3 papers on the application of the subjects in the next 5 years, will that be enough to show competency in the topics on my future career applications?
