What is Dynamic Equilibrium Solutions in FEA about?

This document summarizes a lecture on solving dynamic equilibrium equations using finite element analysis. It describes transforming the equations using a transformation matrix P to decouple the equations. P is chosen as the matrix of eigenvectors from solving the generalized eigenvalue problem Kφ = λMφ. This transformation diagonalizes the equations so they can be solved independently as xi + ωi^2xi = φi^TR, providing the mode shapes and natural frequencies of the system.
