A hypoplastic macroelement for single vertical piles in sand subject to three-dimensional loading conditions

Abstract : This paper presents a novel macroelement for single vertical piles in sand developed within the hypoplasticity theory, where the incremental nonlinear constitutive equations are defined in terms of generalized forces, displacements and rotations. Inspired from the macroelement for shallow foundations of Salciarini and Tamagnini [Acta Geotechnica, 4(3):163--176, 2009], the new element adopts the intergranular displacement mutuated from Niemunis and Herle [Mechanics of Cohesive--Frictional Materials, 2:279--299, 1997] to reproduce the behavior under cyclic loading. Analytical and numerical strategies are provided to calibrate the macroelement's parameters. Comparisons with experimental results show the performance of the macroelement that while being simple and computational fast is suitable for finite element calculations and engineering design.
