Experimental Validation of Nonlinear Shell Structural Dynamics

Experimental results of a beamlike plate have been compared to a nonlinear finite element model. Predicted and experimented results for large displacements and rotations in space caused by static loads show excellent agreement. Time history dynamic analysis of the moving structure was performed and...

Zusammenfassung:	Experimental results of a beamlike plate have been compared to a nonlinear finite element model. Predicted and experimented results for large displacements and rotations in space caused by static loads show excellent agreement. Time history dynamic analysis of the moving structure was performed and showed rather good results compared to experimental results even though no damping was present in the model.
