This study proposes a stabilized implicit Material Point Method (MPM) for incompressible viscous fluids. The weak forms of the equation of motion and continuity equation were coupled and discretized by MPM in space and Newmark’s β method was used in the time domain. Additionally, stabilization methods were introduced to avoid pressure oscillations and unphysical volume shrinkage. The dambreak flow analysis was conducted to validate the developed method including the effectiveness of the stabilizations and implicit scheme.
