Dynamic Substructuring of Geometrically Nonlinear Finite Element Models Using Residual Flexibility ures are assembled using Component Mode Synthesis (CMS). The performance of the free-interface method of Rubin as a linear basis for nonlinear substructuring is examined by implementing the proposed methods on an academic example developed in a commercial finite element software. The accuracy of the

However, making key design decisions based solely on the results obtained from these CAE models requires that the models be verified and validated by comparing the model predictions with kn

Yusuke Inoue,Tomoyuki Yokota,Yoshiaki Takewaent models made from linear elastic materials. This methodology separates the full order model into smaller subcomponents and reduces the equations of motion with a truncated set of fixed-interface modes and static constraint modes. A drawback of this approach is that the model has one constraint mo

While this constitutive model has been validated experimentally, its drawback lies in the difficulty of identifying the correct coefficients. This work proposes a parameter estimation approach using a genetic algorithm to minimize the residual b

Unfortunately, nearly all real engineering structures are assembled from multiple parts, joined by bolts, rivets, or other fasteners, and these joints introduce nonlinearities and uncertainties into systems’ structural stiffness and damping.

The Patterns of Adaptive Learning Surveycture under study is a moored axisymmetric floater with various bilge configurations, whose hydrodynamic properties are of interest. The system is partitioned into a physical substructure, consisting of a scaled model of the floater, and a numerical substructure, consisting of 12 mooring lines. All
