COGGE Webinar - 6/20/2024: Numerical modeling of large deformation problems in Geotech. Engineering

Ғылым және технология

Catastrophic infrastructure failure often stems from the dynamic interaction of soil and water, typically resulting in liquefaction and lateral spreading. Modeling behavior beyond the point of failure needs to account for the complex interactions between solid and liquid phases, the transition from solid behavior to sediment transport, and the issues associated with large deformations. The Material Point Method (MPM) stands out as particularly effective for numerical modeling of large deformations, but is limited in terms of resolution and scale due to computational costs. In this context, Graphics Processing Unit (GPU)-based MPM implementations can accelerate MPM programs by up to 100 times. Current hardware trends indicate that GPUs will become increasingly viable, with expected advancements in video memory, bandwidth, computational cores, and accessibility over the next four years. This presentation reviews these aspects, highlights trends, opportunities, and challenges, and explores the prospects for liquefaction simulation.
