Bounding surface model for sands under cyclic loading
Modification of the original bounding surface hypoplasticity model proposed by Wang et al (1990) to extend it to simulate a wide range of sands, dense and loose, under either cyclic or monotonic loading with but a single set of parameters.

Hydromechanical coupling with RKPM
- An iterative numerical procedure for solving the hydromechanical coupling system. A so-called relaxation term is introduced to stablize the iterative procedure and make it unconditionally stable.
- Solid and fluid phases are both discretized using Reproducing Kernel Particle Methods.
