Orestis’ current interests include: <h4>Element-level soil response under partially drained conditions</h4> <p>Element testing of soils has typically been conducted under undrained or fully drained conditions. Constitutive modelling typically aims to reproduce soil behaviour under these “standard” conditions of drainage. However, there are some problems where partially drained conditions can become more appropriate. This work aims to reveal how soil responds under partially drained conditions using element testing (e.g., <a rel="noopener" href="https://www.icevirtuallibrary.com/doi/full/10.1680/jgeot.21.00082" target="_blank">[1]</a>, <a href="https://www.jstage.jst.go.jp/article/jgssp/10/32/10_v10.OS-21-06/_article/-char/ja/">[2]</a>, <a href="https://www.jstage.jst.go.jp/article/jgssp/10/23/10_v10.OS-12-05/_article/-char/ja/">[3]</a>) to assess how constitutive models perform in capturing this response and propose appropriate modifications (e.g., <a href="https://www.sciencedirect.com/science/article/pii/S0266352X24002313">[4]</a>, <a href="https://www.jstage.jst.go.jp/article/jgssp/10/19/10_v10.OS-8-04/_article/-char/ja/">[5]</a>, <a href="https://www.issmge.org/uploads/publications/51/119/NUMGE2023-343.pdf">[6]</a>). </p> <h4>Partially drained response for offshore applications</h4> <p><span style="font-size: 11.0pt; line-height: 107%; font-family: 'Arial',sans-serif; mso-fareast-font-family: Calibri; mso-fareast-theme-font: minor-latin; mso-ansi-language: EN-GB; mso-fareast-language: EN-US; mso-bidi-language: AR-SA;">Uncertainty regarding the water drainage response in offshore sands often hinders design optimisation. For instance, as monopile diameters increase, the assumption of a fully drained response becomes less appropriate. This work uses element-level observations and modelling capabilities for partial drainage to investigate the partially drained behaviour of offshore foundations.</span></p> <h4>Liquefaction susceptibility of layered deposits</h4> <p>One of the most significant aspects of liquefaction research has to do with the assessment of liquefaction susceptibility, typically performed by practicing engineers using simplified, stress-based or energy-based methods. This work investigates the effects of layer interaction, which are typically neglected by current methodologies (e.g., <a rel="noopener" href="https://www.icevirtuallibrary.com/doi/full/10.1680/jgeot.21.00082" target="_blank">[1]</a>, <a href="https://www.icevirtuallibrary.com/doi/full/10.1680/jgeot.16.P.090">[7]</a>).</p> <h4>Shallow founded structures and earthquake-induced liquefaction</h4> <p>Granular soils found below the water table can liquefy when subjected to seismic shaking. Structures with shallow foundations founded on liquefiable deposits can suffer excessive settlement and rotation in the event of an earthquake. This work investigates the interaction between the liquefiable soil and the structure, focusing on the deformation mechanisms that develop in the soil, the settlement and the rotation of the foundation, as well as at the interaction between neighbouring structures (e.g., <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/eqe.3665">[8]</a>, <a href="https://www.icevirtuallibrary.com/doi/full/10.1680/jgeot.19.P.077">[9]</a>, <a href="https://www.icevirtuallibrary.com/doi/full/10.1680/jgeot.19.P.277">[10]</a>, <a href="https://www.sciencedirect.com/science/article/pii/S026772612100141X">[11]</a>, <a href="https://www.icevirtuallibrary.com/doi/full/10.1680/jgeot.17.P.067">[12]</a>). </p>
