Profile

Assistant Professor in the field of Mechanical Engineering

Dr Ashish Rajak is an Assistant professor in Manufacturing and Design at the Department of Mechanical Engineering, IIIT Jabalpur, India. He has received his PhD degree in High Strain Rate Metal Joining Technique from IIT Guwahati. His research area spans from materials science to manufacturing applications with a primary focus on numerical modelling and simulation on high strain rate metal forming and joining techniques. His research vision is to understand the material behaviour at high strain rate forming techniques. He works in the area of designing metal crimping, clinching, forming, and welding using the Electromagnetic and Vaporizing Foil Actuator System. He worked as a Post Doctorate Researcher for more than a year in the Impulse Manufacturing Laboratory, at Ohio State University, the USA after his PhD. In Impulse laboratory, he took on the challenging task of starting to develop formal shock-physics methods to look at the consolidation and behaviour of metallic powders and continued work on electromagnetic forming and the development of field shapers. He developed brand new techniques, instrumented them with photon Doppler Velocimetry and presented results to the sponsors. He also worked for the US Santiago Project and Honda – American Motors during his tenure.
