Soil is an engineering material which is not a coherent solid material like steel or concrete. It is important to understand the behavior of different type of soil as to an engineer it is a material which can be - built on foundations to buildings, bridges; built in tunnels, culverts, basements; built with roads, runways, embankments, dams; supported retaining walls, quays etc.

Engineers are primarily interested in the mechanical properties of soils - strength, stiffness, permeability that depend primarily on the nature of the soil grains, the state of stress, the water and air contents and unit weight. Depending on the strength and soil condition liquefaction may occur due to earthquake shaking or other rapid loading. Liquefaction and related phenomena have been responsible for tremendous amounts of damage in historical earthquakes around the world.

In our laboratory, we are working on constitutive modeling of soils to describe mechanical properties of soils at different conditions. Our research works involve - laboratory element tests, model tests and numerical simulations with finite element method. Here, we are doing research most of the fields in the geotechnical engineering that can be visually described with the following figure.
