An Infinitely Large Solid Mechanics Napkin (this title, and visual styles, are stolen from Evan Chen's project) is my collection of notes from undergraduate and graduate solid mechanics courses, mostly taken from my time as a teaching assistant for 2.002 Mechanics and Materials II, the upper-level undergraduate solid mechanics course at MIT. I had the privilege of working with and learning from Professor Ken Kamrin and Professor Carlos Portela as they introduced 60-70 students each year to the world of solid mechanics. (Yes, I drew a lot of potatoes.) For the most part, the notes closely follow the course textbook, Introduction to Mechanics of Solid Materials by Anand, Kamrin, and Govindjee (Oxford University Press, 2022). A few sections generalize the results beyond the scope of the undergraduate course (e.g., to large-deformation elasticity and plasticity).

My purpose in posting these notes publicly is to offer them as a reference to those who might find them useful, alongside the many wonderful related resources which can be found in section 0.2 of the PDF. I should say that these notes do not constitute a textbook and shouldn't be used to replace one, nor do they contain nearly enough practice problems to result in mastery of the material. Rather, they are intended as a companion to traditional texts, and I hope that some of the explanations provide a different perspective - something I always appreciated as a student.

You may download the PDF freely and use the notes for personal reasons. Please be aware that this is a work in progress, so the file may be updated at any time. If you do notice an error or omission, please bring it to my attention!
