Hi Sean, Thanks for the lectures above, they are great and extremely useful. I am just looking for a bit of further reading to reinforce where you got all of this theory from, can you recomend a textbook (or books!) that I can study in parallel to all this theory?
Hi @Harry - the book I recommend is Structural Analysis with the Finite Element Method (Volume 2), by Eugenio Oñata. It’s my main source reference for this course.
