About this document
Energy-Momentum Method for 2D Beams by Thomás Verderesi is a document available to read on EtoBox.
This document summarizes an energy-momentum method for the nonlinear dynamics of 2D corotational Bernoulli beams. The method uses cubic interpolation functions to derive consistent inertia and elastic terms in the corotational framework. It employs a shallow arch strain definition and averages axial strains to avoid membrane locking. Most importantly, the energy-momentum method conserves total energy, linear momentum, and angular momentum, maintaining stability and accuracy for long-term analyses of nonline
