2nd JMSE Webinar

Peridynamics and Its Applications in Marine Structures

Marine structures are subjected to harsh marine environment which can cause various damage types including fatigue and corrosion. Prediction of fracture and failure is a challenging research area. There are various methods available for this purpose including well-known finite element (FE) method. FE method is a powerful technique for deformation and stress analysis of structures. However, it has various disadvantages in predicting failure due to its mathematical structure. In order to overcome this problem, a new computational technique peridynamics was introduced. Peridynamics is a meshless method and it is very suitable for predicting crack initiation and propagation in structures subjected to different types of loading and environmental conditions. Peridynamics is also suitable for multiphysics analysis so that influence of different physical fields on each other can be accurately represented with damage prediction capability. In this webinar, various applications of peridynamics for marine structures will be demonstrated including stress corrosion cracking, pit-to-crack transition, underwater shock response of composite structures, fatigue damage prediction in metals, ice-structure interactions and fracture in marine lithium-ion batteries.

Dr. Selda Oterkus joined the department of Naval Architecture, Ocean and Marine Engineering at University of Strathclyde as an assistant professor in August 2015. She is currently an associate professor and the vice-director of PeriDynamics Research Centre (PDRC). She received her PhD degree from the University of Arizona in mechanical engineering with minor degree in civil engineering and engineering mechanics. Her research mainly focuses on multi-physics modelling of materials and structures as far as damage and structural failure is concerned. Thus, her research interests include computational simulations of damage prediction in structures under various loading conditions such as thermomechanical loading, hygrothermal loading and fluid flow. In this sense, she is interested in a new method, Peridynamics, which is a very powerful technique for damage prediction. She is also working on peridynamic material model development such as thermoelasticity, viscoelasticity and plasticity. Dr. Oterkus was a visiting professor at Stanford University (USA), University of Padova (Italy) and Otto von Guericke University (Germany). She is a Special Issue Editor for Computational Material Science (Elsevier) and Journal of Mechanics (Cambridge). She is a member of the editorial boards of Scientific Reports (Springer Nature) and Journal of Peridynamics and Nonlocal Modeling (Springer).

Webinar Content

On Friday 10 September 2021, MDPI and the Journal of Marine Science and Engineering organized their 2nd webinar, entitled "Peridynamics and Its Applications in Marine Structures".

The introduction and first talk were held by the Chair of the webinar, Dr. Erkan Oterkus, from the Department of Naval Architecture, Ocean and Marine Engineering, University of Strathclyde, Glasgow, United Kingdom. His presentation was entitled “Introduction to Peridynamics”. His research is mainly focused on computational mechanics of materials and structures by using some of the state-of-the-art techniques including peridynamics and inverse finite element method. Some of his recent research is focusing on multiscale modelling of stress corrosion cracking, underwater shock response of marine composite structures, failure analysis of electronic packages, collision and grounding of ships and real-time monitoring of ship structures.

Dr. Selda Oterkus, from the Department of Naval Architecture, Ocean and Marine Engineering, University of Strathclyde, Glasgow, United Kingdom, gave the second presentation entitled “Multiphysics Analysis by Using Peridynamics”. Her research mainly focuses on multi-physics modelling of materials and structures as far as damage and structural failure is concerned. Thus, her research interests include computational simulations of damage prediction in structures under various loading conditions such as thermomechanical loading, hygrothermal loading and fluid flow. In this sense, she is interested in a new method, Peridynamics, which is a very powerful technique for damage prediction.

The presentations were followed by a Q&A and a discussion, moderated by the Chair. The webinar was offered via Zoom and required registration to attend.
