Fast Crash Analysis of 3D Beam Structures Based on Object Oriented Formulation 2004-01-1728

The paper presents an Object Oriented Formulation (OOF) of the FE method. The new formulation encompasses models based on traditional FE and Super Element modeling, rigid body mechanics as well as models based on experimental evidence. The first computer implementation of new algorithm addresses dynamic response of arbitrary thin-walled 3D frame structures discretized into SuperBeam Elements and subjected to large dynamic crash loading. The paper presents basics of the general algorithm and element formulation. The theoretical part is followed by the discussion of benchmark tests and results of the application to real world structures.
