Mechanical And Electro-Chemical Investigation Of Carbon Farbric/Epoxy And Aluminum Foam Sandwich Composite Beams, Narin Sara Fatima
Mechanical And Electro-Chemical Investigation Of Carbon Farbric/Epoxy And Aluminum Foam Sandwich Composite Beams, Narin Sara Fatima
Wayne State University Theses
In this study the mechanical and electrochemical response of a sandwich composite comprising of carbon fiber fabric skin and aluminum foam core was evaluated. The three point flexural test was chosen to investigate the mechanical behavior in terms of finding the deformation and failure behavior. The flexural test exhibited an excellent bond between the skin and the core. The specimens mainly failed in three different modes - indentation, core shear and face yielding and showed three distinct regions: a linear rise in load with displacement region, a rapid load drop region and a plateau region followed by a densification region. …

Civil and Environmental Engineering Faculty Research Publications
A reliability-based optimization (RBO) procedure is developed and applied to minimize the weight of eight fiber-reinforced polymer composite bridge deck panel configurations. The method utilizes interlinked finite element, optimization, and reliability analysis procedures to solve the weight minimization problem with a deterministic strength constraint and two probabilistic deflection constraints. Panels are composed of an upper face plate, lower face plate, and a grid of interior stiffeners. Different panel depths and stiffener layouts are considered. Sensitivity analyses are conducted to identify significant design and random variables. Optimization design variables are panel component ply thicknesses while random variables include load and material …
