Dear members,

KIVI Geo is organizing an interesting evening lecture in our faculty. The link to the event is https://www.kivi.nl/afdelingen/geotechniek/activiteiten/activiteit/lezingenavond-geotechniek-1

The event is going to be held in English! Feel free to join and learn about the last developments in Geotechnics.

The English description of the event is as follows:

Research program into self-healing processes in clay

by Anne-Catherine Dieudonné, Assistant Professor of Engineering Geology, TU Delft

The safety, sustainability, and efficiency of many geotechnical strongly rely on the performance of clays, which are used as a natural or engineered barrier to limit fluid flow and pollutant transport. While considerable research effort has been put into the study of crack initiation and propagation, laboratory and field tests have also shown that cracks and fractures in clays have the capacity to naturally close and that the material can partially recover its intact properties. Property is known as self-healing. In this lecture, I  will present a new research program initiated at TU Delft to investigate the fundamental mechanisms responsible for self-healing of clays. Challenges and potential solutions in both experimental testing and modeling at various scales will be addressed.

Centrifuge modeling of offshore wind turbine foundations

By: Dr. Amin Askarinejad, Assistant Professor of Experimental Soil Mechanics, TU Delft

Monopiles are used as the basis for more than 85% of offshore wind turbines. There are, however, some uncertainties regarding the behavior of these large diameter stiff poles that are subjected to large overthrowing cyclic moments. The design codes for these foundations are mainly based on slender posts that are commonly used for offshore oil and gas installations. This lecture presents the lessons learned from an ongoing research program into the physical modeling of offshore wind turbine foundations.

Recent progress in the material point method in Geo-engineering

By: Phil Vardon, Professor of Soil Mechanics, TU Delft

The "material point method" (MPM) promises to be able to simulate large distortions, such as slope failure, during the entire process. This is a significant advance over other numerical methods, such as the finite element method (FEM), where only the beginning of the failure can be predicted. Despite promising early results, there are still a number of problems that affect the accuracy of the method. During this lecture, recent progress is presented to address these issues, along with geotechnical examples to demonstrate their performance.

Research into monopiles using the geotechnical centrifuge

By: Tristan Quinten, Ir.

In this lecture, I tell about my research and the conclusions that I have carried out for my Master's thesis. The subject is the design and verification of a scaled piling rig for research into the pivotability of monopiles using the geocentrifuge. The emphasis here is on the pore pressure development in the surrounding soil body as a function of depth and radial distance to the pile.
