Faculty

Professor Das obtained his PhD in Mechanical Engineering from the Indian Institute of Technology Patna and his MTech in Applied Mechanics from the Indian Institute of Engineering Science and Technology, Shibpur.

He began his career as a Post-Doctoral Researcher at the Indian Institute of Technology Bombay. There, he worked to assess the material's low cycle fatigue and ratcheting performance for cryogenic application. Thereafter, he worked as Senior Engineer in the Methods Team at General Motors-TATA Consultancy Services, Bangalore 

He has about 15 international publications in highly recognized journals such as the International Journal of Fatigue, Theoretical and Applied Fracture Mechanics, and the International Journal of Hydrogen Energy. He has already amassed 200 citations to his publications. 

He has conducted research work in collaboration with Tata Steel Limited, Jamshedpur, and General Motors, among others, to correlate laboratory-level experiments with a complete structural component failure analysis.

 He also serves as a reviewer for highly rated journals in the field of design such as Material Science and Engineering A, International Journal of Fatigue, and International Journal of Hydrogen Energy.

Professor Das’ research focuses on the analysis of damage and deformation of engineering materials encountered during the service period of engineering components through Experiments and Constitutive Material Modelling. My interests span a wide range of research challenges that analyze the application of engineering materials and knowledge of Mechanics of solids and Machine Design in the safe design of an engineering component. A few of the areas are:

Low cycle and high cycle fatigue damage of Additive manufacturing and conventional materials

Design of biomedical implant

Constitutive Material Modelling (UMAT)- isotropic and kinematic hardening model

Ratcheting fatigue damage of metallic materials

Hydrogen embrittlement-fatigue interaction of high strength steel
