Lecture
Finite Element Modeling
Description
This lecture covers the derivation of the equation of motion for a mass density, interpolation introduction for finite elements, Newton's equation for continuum mechanics, and the integration for displacement. It also discusses the mass and stiffness matrices, stability of Newmark method, and energy conservation verification. The lecture concludes with the implementation of explicit Newmark scheme and the importance of natural frequencies and mode shapes in structural dynamics.
