Bio Inspired Blast Resistant Marine Sandwich Structures
Abstract
Marine structures are normally subjected to harsh loading environments such as shock or blast loadings. The motivation for this work being the ability of woodpecker beak, (whose configuration is in the form of sutures) in resisting very high amplitude loading without resulting injury to any part of its body. In this proposed project, a new super convergent finite element model with viscoelastic properties will be developed. There different viscoelastic models, namely, a simple Kelvin-~~Void model, Maxwell model, and the Kelvin model will be used to formulate different finite element. About 10 different suture designs will be studied for its energy absorbing properties and optimization of the suture parameters will be performed to obtain the optimum properties of the identified suture design to obtain maximum energy absorption. The last part of the project deals with developing a new finite element for the marine sandwich structures that have these sutures at the interface between the face sheet and the core. The proposed project will also be aimed at developing new computational framework for analyzing new hybrid marine sandwich composites that is resistant to blast and shock loadings
