Dr Selda Oterkus

Lecturer

Naval Architecture, Ocean and Marine Engineering

Personal statement

Dr. Selda Oterkus joined the department of Naval Architecture, Ocean and Marine Engineering at University of Strathclyde as a lecturer in August 2015.

She received her PhD degree from the University of Arizona in mechanical engineering with minor degree in civil engineering and engineering mechanics. She worked both as a research and teaching assistant during her PhD studies.

Her research mainly focuses on multi-physics modeling of materials and structures as far as damage and structural failure is concerned. Thus her research interests focuses on 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.

As the application of the model development, she is working on many problems that involves multiphysics simulation of complex material behavior.

Simulation of hydraulic fracturing is a good example for this. The analysis includes coupling of mechanical deformation, flow in porous media and fracture prediction.

Another area that she is working on is the thermal fracturing behavior of fuel pellets. Fuel pellets are used in nuclear reactors for the power generation of submarines and naval ships. Performance of nuclear reactor is influenced by the thermo-mechanical behavior of the pellets.

She is also working on failure prediction in electronic packages. Electronic packages normally include polymer components and these polymer components can absorb moisture during shipping or storage. During the soldering process to join different components of the package at very high temperatures, the absorbed moisture can turn into vapour. As a result cracks can occur. Therefore, she developed a peridynamic model which couples moisture, temperature and structural fields with failure prediction capability.

In addition to her experience with Peridynamics, she also uses Finite Element Method to investigate stiffened structures and wind turbine blades.

She is very interested in collaborative work with industrial and academic partners.

 

Dr. Oterkus was a visiting professor at Stanford University (USA), University of Padova (Italy) and Otto von Guericke University (Germany). She is a member of the editorial boards of Journal of Peridynamics and Nonlocal Modeling (Springer), International Journal of Science and Qualitative Analysis and EPH-International Journal of Science and Engineering.
