CEE GEOTECH Seminar: Mohmad Mohsin Thakur
Title: "Towards Modeling Projectile Penetration in Dry and Multiphase Granular Materials"
The projectile penetration in granular materials such as sands has been a subject of research for more than five decades. This talk will discuss the development and validation of numerical modeling strategies in granular materials impacted by a projectile.
Both dry and multiphase granular materials will be discussed in context to the projectile penetration boundary value problem. The focus is on two regions: (a) near-field: region near the tip and along the path of a projectile where comminution of grains is significant, (b) intermediate-field: region far from the projectile where grain-scale interactions are important but stresses are not high enough to cause crushing of the grains. The reliable numerical modeling of projectile penetration in sands requires high fidelity input in terms of grain shape, realistic grain and pore microstructure, advanced material models, accurate representation of boundary conditions, realistic distribution of pore fluids in case of multi-phase granular materials, and high-quality experiments for validation.
Mohmad Mohsin Thakur is a postdoctoral fellow at Hopkins Extreme Materials Institute, John Hopkins University. He completed his PhD at the University of Tennessee, Knoxville (UT). His research is on understanding the micromechanics of granular materials such as sands and cementitious composites. He uses experiments, numerical modeling, and computational topology to explore research problems. His doctoral work at UT earned him editor’s choice paper in the Journal of Geotechnical and Geoenvironmental Engineering, ASCE; first place in Oak Ridge Chapter of American Society of Materials student award, and runner up in The Modeling Inelasticity & Multiscale Behavior Committee Student Paper Competition in Engineering Mechanics Institute Conference, at Caltech.
