Abstract

Modeling and prediction of response of swelling clays to external stress is an important area of research in poromechanics and has applications in the fields of geotechnical engineering, petroleum engineering and materials science. A common clay mineral responsible for swelling in swelling clays is montmorillonite. Water in the interlayer of Na-montmorillonite plays a significant role in the swelling, swelling pressure and resulting changes in the microstructure and mechanical properties of the swelling clay. Here, the molecular interactions between water and clay in the interlayer are described and the quantitative mechanical responses of the interlayer to external stresses are evaluated using steered molecular dynamics simulations under varying external stresses and hydration. © 2005 Taylor & Francis Group, London.
