Boundary value problems are also called field problems. The field is the domain of interest and most often represents a physical ://~mech/lectures/ Damping is a great way to limit the vibrations. We use a lot «static» analysis in FEA but in reality, most of the dangerous phenomena which are dangerous are dynamic That’s why a basic dynamic analysis is the «modal» analysis which uncovers the core mode of vibrations which can potentially create problems when excited by some The book The Finite Element Method has the full explanation for how this is developed (Chapter 1 goes over the basics of the method, and Section develops the frequency analysis portion).
Just to clarify, we've simply called these matrices K and M, and the form of the equation bears a resemblance to a simple modal analysis for a beam, so we //understanding-finite-element-modal-analysis.
