Yielding and Progressive Failure of Composite Materials
Abstract
Research will be conducted into the mechanical behavior and failure of marine composite materials (woven textile) and composite sandwich plates with PVC foam cores and balsa wood cores, when subjected to severe threats. Carbon fiber and glass fiber/vinylester composites (RTM) will be studied. failure modes in composite sandwich plates under impact loads will be established. Mitigation aspects will be addressed. -Characterization and modeling of composite materials and foam cores is needed for implementation of numerical models capable of capturing the dynamic response of composite and sandwich structures under realistic impact and blast loadings and design naval structures for Mitigation of severe threats. the goal of the proposed Research is to gain a better understanding of the mechanics of marine structures made of composite materials, when subjected to high energy, high velocity dynamic loading. This is accomplished by Characterization and modeling of the three-dimensional static and dynamic response of the constituents as well as the laminates and sandwich structures.A98
