Creating Data-Driven Reduced-Order Models for Nonlinear Vibration via Physics-Informed Neural Netwoent cases, but this approach has previously been demonstrated to be overly dependent on the scale of these characteristics, a point that has prevented wider application. In this work, initial steps are taken to utilise physics-informed recurrent neural networks (RNNs) in place of the static step, al作者: ARCH 時(shí)間: 2025-3-22 02:50 作者: Spina-Bifida 時(shí)間: 2025-3-22 08:15 作者: 仇恨 時(shí)間: 2025-3-22 08:58

Modeling Nonlinear Structures Using Physics-Guided, Machine-Learnt Models, where a neural network is used to directly model the Lagrangian function of the system. To enforce physical consistency, the Euler-Lagrange equations of motion of the system are obtained by differentiating this neural network using automatic differentiation techniques.
