SUMMARY:Characterizing Dynamic Response of Structures and Materials under Extreme Loading Environments
DESCRIPTION:Protective structures and vessels used in marine and defense applications are increasingly required to withstand extreme dynamic loading caused by explosions in air and underwater. Designing lightweight yet resilient structures demands a fundamental understanding of shock-wave interactions with materials\, structural geometry\, and the surrounding medium. This seminar presents a series of experimental investigations that progressively examine these aspects using advanced diagnostics.\nThe seminar begins with a comparative study of circular composite plates subjected to planar shock loading in air and underwater. The experiments reveal how the loading medium governs structural deformation\, vibration characteristics\, and cavitation-induced secondary loading\, providing insights into shock–structure interaction.\nNext\, the influence of structural geometry is examined through blast experiments on curved polymeric sandwich composite panels. The effects of curvature and boundary conditions on structural response are investigated\, demonstrating that geometric tailoring can significantly enhance blast resistance and modify damage mechanisms.\nThe seminar concludes by exploring the complex interaction between near-field underwater explosions and sandwich composite structures. Experimental observations capture the coupled effects of shock waves\, gas-bubble oscillations\, surface cavitation\, and structural deformation. The results highlight the influence of explosive stand-off distance and core density on impulse transfer\, cavitation dynamics\, and failure mechanisms\, providing valuable insights into fluid–structure interaction under extreme underwater loading.\nTogether\, these experimental studies advance the understanding of the dynamic response of composite structures under extreme loading and provide guidance for the design of resilient lightweight structures for naval\, offshore\, and protective engineering applications.\n\nSpeaker: Dr. Akshay Pandey\n\nBiography:\nDr. Akash Pandey is currently working as a Research Associate at the University of Cambridge. He previously worked at the Indian Space Research Organisation (ISRO) before earning his Ph.D. from the University of Rhode Island. His research focuses on the dynamic response of structures and materials subjected to extreme loading conditions\, including blast and impact

SUMMARY:FROM MOTION PLANNING TO MULTI-ROBOT AUTONOMY IN CONSTRAINED AND DISCONNECTED ENVIRONMENTS
DESCRIPTION:Autonomous robots operating in challenging environments must make reliable decisions under geometric\, dynamic\, and environmental constraints. In such settings\, motion planning plays a central role in enabling robots to move safely and efficiently through cluttered\, narrow\, disconnected or uncertain spaces\, while balancing feasibility\, robustness\, and computational efficiency. \nThis talk will focus on motion planning for quadrotors flight through constrained regions such as narrow windows and cluttered spaces. In the later part of the talk\, I will briefly broaden the discussion to autonomy problems beyond single-robot flight\, including hierarchical coverage path planning in disconnected regions and terrain-aware balanced area allocation for heterogeneous multi-robot systems. Together\, these works highlight how planning methods must scale from vehicle-level motion generation to higher-level coordination and task allocation in challenging operational environments. \nSpeaker: Dr. Saurabh Upadhyay \nBiography: \nSaurabh Upadhyay received B.E. degree from SSGMCE\, Shegaon in 2009\, M.Tech. degree from IIT Guwahati in 2012\, and Ph.D. degree from IISc Bengaluru in 2018. He is a Lecturer in Space Engineering at Cranfield University\, UK. His research interests lie in mobile robots for extreme environments\, with special focus on low onboard resources decision making and ISRU-enabled robot design. He has received A.K. Rao best PhD thesis medal 2018 in Aerospace Engineering at IISc Bengaluru\, and he is endorsed as a potential leader/exceptional promise by Royal Academy of Engineering in 2021. He is an IEEE senior member\, lifetime AIAA Senior member\, and fellow of HEA.
