Title: A layerwise model for soft core sandwich panels
Issue Date: 2004
Abstract: The application of high damping materials, like high loss factor viscoelastic materials,in the core of sandwich plates can improve their dynamic response and reduce fatiguefailure. However, the numerical simulation of the effects of this kind of dampingtreatment demands a cumbersome computational work, specially during the spatialmodelling task of the layered structure. In this work, a layerwise model is developedand applied in the analysis of sandwich plates with thin viscoelastic cores, comparingthe results achieved with those obtained with the usual modelling approach using alayered combination of standard plate and solid finite elements. The proposed modelcan correctly describe the high shear pattern developed inside the thin viscoelasticcore, providing results similar to those obtained with the layered models.
