Effect Of Slope Angle On The Runout Evolution of Granular Column Collapse for Varying Initial Volumes
Qiuyu Wang, Reihaneh Hosseini, Krishna Kumar
In nature, submarine slope failures usually carry thousands of cubic-meters of sediments across extremely long distances and cause tsunamis and damages to offshore structures. This…
Investigating the Thixotropic Behaviour of Tremie Concrete Using the Slump-flow Test and the Material Point Method
Christopher Wilkes, Krishna Kumar, Giovanna Biscontin
A new thixotropic model is developed integrating the Papanastasiou-Bingham model with thixotropy equations to simulate the flow behaviour of Tremie Concrete in the Material Point M…
Investigating the effect of porosity on the soil water retention curve using the multiphase Lattice Boltzmann Method
Reihaneh Hosseini, Krishna Kumar, Jean-Yves Delenne
The soil water retention curve (SWRC) is the most commonly used relationship in the study of unsaturated soil. In this paper, the effect of porosity on the SWRC is investigated by…
Effect of Initial Volume on the Run-Out Behavior of Submerged Granular Columns
Qiuyu Wang, Reihaneh Hosseini, Krishna Kumar
Submarine landslides transport thousands of cubic meters of sediment across continental shelves even at slopes as low as 1° and can cause significant casualty and damage to infrast…
Modeling irregular boundaries using isoparametric elements in the Material Point Method
Ezra Y. S. Tjung, Shyamini Kularathna, Krishna Kumar +1
The Material Point Method (MPM) is a hybrid Eulerian-Lagrangian approach capable of simulating large deformation problems of history-dependent materials. While the MPM can represen…
Scalable and modular material point method for large-scale simulations
Krishna Kumar, Jeffrey Salmond, Shyamini Kularathna +4
In this paper, we describe a new scalable and modular material point method (MPM) code developed for solving large-scale problems in continuum mechanics. The MPM is a hybrid Euleri…
