CMS with Large Contact Patches,tructures for structural dynamics modeling. When the interfaces between these substructures are of limited complexity, such as a discrete set of bolts, these approaches work well, providing compact and portable models. With large interfaces relative to the volume, such as contact patches, these appr

In Situ Measurements of Contact Pressure for Jointed Interfaces During Dynamic Loading Experiments, pressure within a joint. Previous approaches have focused on static measurements, typically taken separately from the dynamic testing of a jointed system. In this research, an electrical contact pressure measurement system is used to measure the contact pressures within a jointed interface during d

Substructuring of a Nonlinear Beam Using a Modal Iwan Framework, Part I: Nonlinear Modal Model Idendeled on a mode-by-mode basis. The method relies on the fact that the modes of a weakly nonlinear structure tend to remain uncoupled so long as their natural frequencies are distinct and higher harmonics generated by the nonlinearity do not produce significant response in other modes. A single degre

Dynamic Substructuring of Geometrically Nonlinear Finite Element Models Using Residual Flexibility ce the model order of a geometrically nonlinear structure, the closed form equations of motion for the substructures are classically required. However, in industrial applications these equations are often not available, because the model of interest is constructed in a commercial finite element soft
