Abstract Summary
Cyclic loading is crucial for the design under lateral loading of monopile foundations of offshore wind turbines. Finite element analysis of the monopile under cyclic loading is necessary. However current advanced constitutive models fail to capture adequately cyclic loading of sand. Results of HySand, a new multisurface model developed in the hyperplastic framework, will be compared to data by Wichtmann on Karlsruhe fine sand. The focus will be on complex triaxial tests, including cyclic stress and strain-controlled undrained tests.
