Liu, H. (author), Kementzetzidis, E. (author), Abell, J. A. (author), Pisano, F. (author)Serviceability criteria for offshore monopiles include the estimation of long-term, permanent tilt under repeated operational loads. In the lack of well-established analysis methods, experimental and numerical research has been carried out in the last decade to support the fundamental understanding of monopile-soil interaction mechanisms, and...journal article 2021

Liu, H. (author), Abell, J. A. (author), Diambra, A. (author), Pisano, F. (author)The modelling and simulation of cyclic sand ratcheting is tackled by means of a plasticity model formulated within the well-known critical state, bounding surface SANISAND framework. For this purpose, a third locus – termed the ‘memory surface’ – is cast into the constitutive formulation, so as to phenomenologically capture micro-mechanical,...journal article 2019
