Project Details

Title:Reliable Prediction of Shear Strength of Swelling Clays
Principal Investigators:Dinesh R. Katti and Kalpana S. Katti
University:North Dakota State University
Project #:MPC-506
RiP #:01598863
Keywords:clay soils, infrastructure, mathematical prediction, microstructure, shear strength, swelling soils


Bridging the molecular interactions to the evolution of microstructure and bridging both molecular interactions and microstructure to the mechanics of the swelling clays will provide powerful predictive capabilities and develop a clear understanding of underlying mechanisms that lead to shear strength properties in swelling clays. Specific objectives are 1) Construction of multiscale computational simulations test-beds for swelling clays to evaluate the role of molecular interactions and microstructure to macroscale shear strength properties of swelling clays; 2) Development of experimental techniques to evaluate the swelling clay-fluid interactions and mechanical properties at various length scales: molecular scale to macroscale.
