Parametric reduced-order models via SSMs for imperfect structures
Abbreviations Context Complex mechanical structures are typically analysed using FE models with hundreds of thousands to millions of DOFs. Computing their nonlinear dynamic response can be prohibitively expensive, as internal forces and, for implicit solvers, tangent stiffness matrices must be repeatedly evaluated during time integration. Reduced-order models address this challenge by describing the dynamics through…
