Research Area

The broad spectrum of research are behaviour of Granular soils, Model testing, Constitutive modelling, Discrete Element Modelling, Reliability analysis, Geo-environmental problems and Sustainability through LCA and LCEA from geotechnical point of view. Granular soil behaviour has direct correlation with particle arrangement and their contact force chain distribution. Hence the macro response can be observed through model testing considering the corresponding natural conditions. But experimental investigations are not always feasible, hence one has to utilize constitutive models for predicting the mechanical behaviours in different conditions. However certain challenges has to be explored microscopically giving adequate importance to particle contacts, which can be carried out using Discrete element modelling. Geo-environmental problems hasgained ultimate importance as humanity is striving for a sustainable world. Hence it is critical to analyse and quantify geo-environmental problems and their Impacts. Geo-structures are designed with strength and stability conditions alone. It is high time to bring in the sustainable aspects to their designs. This can only be possible by quantifying the environmental impacts and minimizing them by analysis using LCA or LCEA
