Abstract:
The aim of the work presented in this thesis is deal with some of the aspects in the FEM analysis of sandwich panels containing holes which comprised with foam core. It is a new topic in this field; so the activities that have been done about this case are poor with respect to its performances in engineering. The main emphasis is placed on the treatment of the foam core since the core often is the weakest part of the sandwich and therefore in many ways governs the capacity and lifetime of the whole sandwich structure. Because of increasing application including construction, aircraft and transportation, marine and etc., different load conditions are considered for the analysis and modeling of these panels. In this research an investigation has done on the experimental results. Then FEM modeling was produced, analyzed and computed considering laboratory conditions. After verification and validation of the model, an extensive parametric study was investigated under different load conditions; different geometrical parameters, such as; dimensions, face thickness, core thickness, size and location of the opening.
