Brief Bio: Dr. Abhishek Tiwari completed B.Tech. in Metallurgy from NIT Jamshedpur (2008). He worked in Essar Steel Hazira Ltd. and Institute for plasma research. Following which, he did M.Tech. from IIT Kharagpur (2012). He worked on stress analysis of helical compression springs loaded under very high cycle fatigue condition as an IIT-DAAD fellow at Technical University Darmstadt, Germany. In his Ph.D. work on Indian Reduced Activation Ferritic/Martensitic Steels in ductile to brittle transition (DBT) regime, he developed a novel constraint loss parameter known as, 'Weibull Triaxiality' and modified analytically the master curve approach to include the events of cleavage fracture in the upper region of DBT. In the year of 2018, he started his postdoctoral work at Erich Schmid Institute of Material Sc. under Austrian Academy of Sciences in Leoben Austria, where he worked for two years. During this period, he worked on application of configurational force concept for improvement of fracture toughness. At IIT Ropar, Dr. Tiwari's main focus would be to understand the mechanics of materials and modelling of damage of materials. Other areas of research would be to design a material structure to enhance the fracture toughness using configurational force based calculations in large scale plastic, creep, cyclic and creep-fatigue conditions.
