TomasSab is a Ph.D. fellow working at Aalborg University, geotechnical laboratory. His work is supervised by Lars Bo Ibsen.
Research of cyclic and transient soil (mainly sand) properties is done using the Danish triaxial apparatus - and improved trixaial apparatus which harnesses isotropic yielding to prevent premature specimen collapse. Due to improved testing capabilities, a specimen can be tested during unorthodox, complex loading scenarios. For example - liquefied, squeezed to failure after liquefaction, then drained, pulled back to initial length and cyclic tested in drained mode to observe post-liquefaction cyclic loading. This is state of the art triaxial testing capacity.
Research of cyclic and transient loaded small scale foundations is done in dedicated sand boxes with saturated sand. These tests are done to observe off shore foundation response, encountered during cyclic and transient loading cycles imposed by waves and wind.
All research TomasSab is working with is primarily focused on solving problems encountered in off shore wind turbine foundation design. But the findings overlap with other fields of geotechnical engineering to a great extent. Findings may apply to seismic and industrial engineering as well.
