I am using <A First Course in Finite Element Method by D.L. Logan because I have the hardcopy. After this I will go for <Finite Element Procedure> by Bathe which is thicker, 1000+ pg.

Hi Aleph, thanks for the explanation. Do you mean that we should consider the sping and external force (invisible hand) as a system? i.e. total potential energy is spring potential energy + invisible hand potential energy? And how should I see the potential energy of the force F, it...

Good day! I am a beginner in Finite Element Analysis and Structural Mechanics. I have problem in understanding the insight of potential energy approach to derive spring element equations. I have already search for similar post and I found this, and agree with the example raise...
