- National Contributions:
Prof. Gupta’s expertise in mechanics of large
deformation of metals and composites under impact loading has been greatly
augmenting the advancement in technology and in particular, Indian defence, and
aerospace researches. He has
been one of the most sought after professor in the IIT system who helped
scientists in defense, aeronautical and other laboratories and institutes
including IISc and IITs in developing
their in-house capabilities. He has been consulted in most of the national designs
involving large deformation and failure under impact or blast loading.- Some of the typical designs where he has made contributions are:
Developing constitutive behaviour for metals and composites and yield criterion for pre strained metals - these have been used in several application oriented computations.
Problems of Naval interest include design of grillage structures for their application to ships and submarines resilient to underwater and air explosions; design of energy absorbing hull structure in order to minimize the transmitted vibration to sensitive equipment on board; estimation of direction of crack growth in damaged structures and design of ship hull under slamming loads in rough seas.
Problems of Aeronautical Research and Development Board which include dynamic response and risk assessment of aircraft components under multi-axial random loads; design of crash absorbing systems, damage resistance of thin walled composite structures under low velocity impact – application to aircraft design; transitions in collapse modes; structural collapse modes of various metals and composite structures; aircraft arrester barrier; crashworthy nose cone design of small aircraft; impact absorbing mechanism of unmanned air vehicles; crashworthy design of helicopter base and landing gear; composite aircraft structures; design of aircraft components and aircraft accident analysis. Some Defence Research and Development projects included several series of studies on blast loading or normal and oblique projectile (rigid, long rod, deformable, jacketed projectiles with cylindrical, spherical and square geometries) impact on single and layered plates (metallic, composite and ceramic) for their applications to design for safety or offence.
He has helped working on devices for measurements of high velocities and deformations; design of fatigue machine; design of friction machine; designing of piping system; high speed cutting processes; high strain rate behaviour of metallic and non-metallic materials and design of drop platform systems.
He has been a mentor to large number of B.Tech, M.Tech and Ph.D students and he continues to be a ‘friend, philosopher and guide’ to them many years after they have graduated and established themselves in leading positions in reputed academic institutions, government research organizations and industry both in India and abroad.
