1. Nonlinear Structural Identification Using a Multi-Harmonic Frequency Response Functions
Sammanfattning : In industrial structural dynamics problems, linear FE-models commonly serve to represent the global structural behavior. However, when test data are available they often show evidence of nonlinear dynamic characteristics. In that case, an initial linear model may be judged insufficient in representing the dynamics of the structure. LÄS MER
2. Model Calibration of Nonlinear Mechanical Systems Using Multi-Harmonic Frequency Response Functions
Sammanfattning : In industry, linear finite element models are commonly employed to represent global structural behavior. It is crucial that the computational models are able to accurately represent the structures’ behavior. This cannot always be achieved by the use of linear models. LÄS MER
