Abstract Details

2011, Master of Science in Engineering, University of Akron, Civil Engineering.
An analytical solution was derived for obtaining the large amplitude, damped response of a crushable foam core sandwich beam subjected to pressure pulse loading. The simply-supported sandwich beam, comprised of aluminum facesheets and a PVC foam core, was analyzed for its response to a uniformly distributed pressure pulse load. The equations of motion for the sandwich beam were developed considering first-order shear deformation and membrane stretching. The initial response of the beam was elastic until the onset of plasticity, when transverse shear stresses in the foam core exceeded the transverse shear yield strength of the foam. The facesheets remained elastic, while the core was elastic-plastic, throughout the entire load – unload cycle. Analytical results were compared to results from finite element analysis using ABAQUS Explicit and good agreement was found between them. The analytical solution can be used to design sandwich beam experiments for extracting foam damping properties.
