RISSimulation-Free Hyper-Reduction for Geometrically Nonlinear Structural Dynamics: A Quadratic Manifold Lifting Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We present an efficient method to significantly reduce the offline cost associated with the construction of training sets for hyper-reduction of geometrically nonlinear, finite element (FE)-discretized structural dynamics ...
Hyper-Reduction Over Nonlinear Manifolds for Large Nonlinear Mechanical Systems
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Common trends in model reduction of large nonlinear finite element (FE)-discretized systems involve Galerkin projection of the governing equations onto a low-dimensional linear subspace. Though this reduces the number of ...
