Stochastic bifurcations in nonlinear discontinuous dynamical systems
We investigate the effects of randomness in the loadings on the dynamical behaviour of discontinuous systems like impacting systems, such as, gears and industrial heat exchangers.
Uncertainty quantification of microstructutral variability in materials across multiple scales
The focus of this study is on characterizing the microstructure scale heterogeneity in materials across multiple scales, with the objective of developing fatigue life measures.
The nonlinear dynamics of flexible flappers in flow is a problem in fluid structure interaction and helps in understanding the dyanmics of swimming fish & flapping of flags. This understanding is used for designing energy harvesters from flows.
Random network theories are used to investigate the dynamics of large ordered complex dynamical systems, such as the growth of a disease or how neuronal network in brains function.
Local and global bifurcations in 3D piecewise smooth discontinuous maps
Bifurcations in higher order piecewise smooth discontinuous maps are investigated and their existence conditions are analysed. Effects of noise on the dynamics is studied.
Targeted energy transfer using nonlinear energy sinks
We investigate the use of nonlinear energy sinks for targeted energy transfer to improve the effeiciency of harvesting energy in flow based energy harvesters.
Stochastic modelling and analysis of fin buffeting
The study focusses on modelling and analysis of buffeting of tail fin in delta winged aircraft and analysizng for fatigue damage considering the random gust effects due to buffeting.
