NICOP - Bio Inspired Adaptive Blast Mitigation Strategies for Marine Sandwich Structures
Abstract
Marine structures are normally subjected to harsh loading environments such asshock or blast loadings. This extended project is aimed at the development ofBio inspired models for marine sandwich composite structures to study the energy absorption effects of shock and blast loadings of high intensity. Here, anew a new suture based design, which is normally found in the many biologicalstructures such as tip of the wood pecker beak, will be explored and study thelevel of energy absorption that can be obtained as a function of suture periodand amplitude. This study will be performed numerically through the development of computational model such as conventional finite elementsand spectral finite elements. Next, a Metamaterial based model will be developed, that will adaptively change the suture period and amplitude toobtain maximum energy absorption. In the last part of this extended project,this suture based meta-~#material model, will be integrated as interface materialbetween the face sheet and the core of a marine sandwich composite structureand the numerical sandwich finite element model will be developed to studythe energy absorption characteristics of this adaptive structure. The proposedproject will also be aimed at developing new computational framework foranalyzing new adaptive hybrid marine sandwich composites under blastand shock loadings.
