TI  - Numerical Simulation of Landslides through a Stabilised Material Point Method with SANISAND Model
AV  - public
N2  - This research presents a new semi-implicit two-phase double-point MPM formulation for modelling
large-deformation geotechnical problems such as landslides. The proposed method addresses instabilities in traditional single-point MPM by using distinct sets of material points to model the soil and
water phases separately (double-point approach). A modified F-bar technique is derived to stabilise
advanced soil constitutive models such as SANISAND, allowing for a more realistic simulation of soil
behaviour. The water phase is solved implicitly, enabling significantly longer time steps compared to
fully explicit MPM approaches. Landslide examples using the SANISAND constitutive model are presented in this paper, demonstrating the performance of the modified F-bar method and highlighting
the importance of the double-point approach.
