摘要: Linear modal analysis is a mature tool enjoying various applications ranging from bridges to satellites. Nevertheless, fails in the presence of nonlinear dynamical phenomena and development practical analog current research topic. Recently, numerical techniques (e.g., harmonic balance, continuation periodic solutions) were developed for computation normal modes (NNMs). Because these methods are limited conservative systems, present study targets NNMs nonconservative systems. Their definition as invariant manifolds phase space considered. Specifically, new finite element technique proposed solve set partial differential equations governing manifold geometry.
