Dr. Uday Shanker Dixit received B.E. degree in Mechanical Engineering from erstwhile University of Roorkee (now Indian Institute of Technology Roorkee) in 1987, M.Tech. degree in Mechanical Engineering from Indian Institute of Technology Kanpur in 1993, and Ph.D. in Mechanical Engineering from IIT Kanpur in 1998. He has worked in two industries-- HMT, Pinjore and INDOMAG Steel Technology, New Delhi, where his main responsibility was designing various machines. Dr. Dixit joined the Department of Mechanical Engineering, Indian Institute of Technology Guwahati, in 1998, where he is currently a professor. He was also the Officiating Director of Central Institute of Technology, Kokrajhar from February 2014 to May 2015. Dr. Dixit is actively engaged in research in various areas of design and manufacturing since last 25 years. He has authored/co-authored 109 journal papers, 104 conference papers, 26 book chapters and 6 books in mechanical engineering. He has also co-edited 7 books related to manufacturing. He has guest-edited 11 special issues of journals. Presently he is an Associate Editor of the Journal of Institution of Engineers (India), Series C and the Regional Editor (Asia) of International Journal of Mechatronics and Manufacturing Systems. He has guided 11 doctoral and 43 masters' students. Dr. Dixit has investigated a number of sponsored projects and developed several courses. Presently, he is the Vice-President of AIMTDR conference. Dr. Seikh Mustafa Kamal obtained a bachelor's degree in Mechanical Engineering from Jorhat Engineering College, Jorhat, Assam, India in 2009 and a PhD in Mechanical Engineering from Indian Institute of Technology Guwahati in 2016. He has served as Assistant Professor of Mechanical Engineering at NITS Mirza, Guwahati for a period of about three years (2009−2012) prior to joining the direct PhD programme at Indian Institute of Technology Guwahati. Dr. Kamal joined the Department of Mechanical Engineering, Tezpur University, Assam, India in 2016, where he is currently an Assistant Professor. He is an active researcher in the area of autofrettage, plasticity and stress analysis. During his PhD, he developed a new thermal autofrettage method for strengthening thick-walled pressure vessels under the supervision of Prof. U. S. Dixit. His recent research interest is in exploring rotational autofrettage. He has published 6 journal papers, 7 conference papers and 2 book chapters on the area of autofrettage. He has edited one conference proceedings (Proceedings of the National Conference on Sustainable Mechanical Engineering: Today and Beyond, 25−26 March, 2017, Tezpur University, India) and guided 2 Masters' students. Mr. Rajkumar Shufen received his bachelor's degree in Production engineering from Birla Institute of Technology and Mesra, Ranchi in 2011 and Master's degree in Engineering Design from Birla Institute of Technology and Science in 2015. He has worked in an US based firm Fluor Daniel Corporation for two years in Gurgaon, India as an Associate Piping Design Engineer. He has earned significant industrial experience in plant design, piping layouts, pump piping and pressure vessels. He is currently pursuing Ph.D. in Mechanical Engineering from Indian Institute of Technology, Guwahati. Since joining his Ph.D. he has published three research journal papers. His research areas include computational solid mechanics, plasticity, pressure vessels and material science
