case 1)in finite element analysis of structures using simple rod elements we do the stiffness matrix and then find the displacements from loads and constraints(adsbygoogle = window.adsbygoogle || []).push({});

case 2)finite element method is a technique for solving partial differential equations. In the case1 what is the partial differential equation and what it looks like?
