摘要: In this paper we assess the performance of finite element models in modeling structures with sheer damping treatments. We analyze constrained layer (CLD) and integrated (ILD) treatments using viscoelastic materials, devoting special attention to spatial treatment characterization material properties. work, used a commercial software (MSC.Nastran) simulate dynamic response aluminum plates both configurations (CLD ILD). The was devel-oped three different models, all based on layered assembly plate/brick conventional elements. properties were taken into account numerical simulation complex modulus approach. results are correlated experimental data obtained for four treated specimens by direct comparison frequency respo...
