Using the discrete Euler-Lagrange and Lagrange-d’Alembert principles, we simulate the behavior by means of variational integrators and, in particular, AVIs (Asynchronous Variational Integrators). We place special emphasis on the geometric structure underlying stress resultant beam models and propose B-spline shape functions for AVI-method.text::conference output::conference proceedings::conference paper
