In-plane dynamic buckling of duoskelion beam-like structures: discrete modeling and numerical results

In this contribution, a previously introduced discrete model for studying the statics of duoskelion beam-like structures is extended to dynamics. The results numerical simulations performed using such an are reported discuss in-plane dynamic buckling under different loading and kinematic boundary conditions. core instrument analysis beam element, which, in addition flexure, also accounts extension shearing deformations. Working setting dynamics, inertial contributions taken into account as well. A stepwise time integration scheme employed reconstruct complete trajectory system, namely before after buckling. It concluded that structure exhibits exotic features compared with classical modeled at macro-scale by Euler–Bernoulli’s model.
