Cyclic loading of soils often involves complex stress and strain paths. In a new paper in the International Journal for Numerical and Analytical Methods in Geomechanics, we investigate the HCA model for complex cyclic loading with multidimensional loading paths and extend it for frequently changing loading amplitudes and directions in numgeo. This extension is validated by simulation of model tests on piles for offshore wind turbines subjected to multidimensional lateral loading with thousands of cycles.
