A computational framework for underwater shock response of marine structures

Composite structures have extensive area of practice in engineering disciplines. One of the application areas is to use them under extreme loading conditions. However, our understanding of their behaviour under shock loading is rather limited. As a result of this, current designs of composite structures are very conservative which significantly reduce the weight saving advantage. In order to improve our understanding, experimental studies are essential but they can be prohibitively costly. On the other hand, computer simulations can be a good alternative. Hence, the main objective of this study is to investigate underwater shock response of marine composite structures by using a new theory called peridynamics. Numerical approach based on peridynamics is used to predict the failure modes in marine composite structures. The evaluated results are validated by comparing against the available data in literature which demonstrates the capability of peridynamics for such complex problems.
