WELCOME TO THE HOMEPAGE OF

PROFESSOR K. V. NAGENDRA GOPAL

 

 

 

 

I am a Professor in the Department of Aerospace Engineering in the Solids and Structures group. My research work spans a range of problems in the broad area of structures made of composites and advanced materials focussed on the modelling and analysis of the mechanics and multiphysics response of these structures. A mix and analytical and numerical methods are used and complemented by experimental work done in collaboration with faculty colleagues and scientists from other organizations.
