Prof. Tasnim Hassan has been a faculty member in the Department of Civil Engineering at North Carolina State University since 1995 after receiving his PhD from the University of Texas at Austin. His research areas include experimentation and constitutive model development for designing against low-cycle fatigue or seismic failure of critical components, steel building structures and welded joints. His constitutive model development studies have been focused on improving simulations for low-cycle fatigue and ratcheting responses of various steels and alloys under uniaxial and multiaxial loading. His research group has developed a detailed computational method for investigating residual stress induced failures of welded joints. The group has developed advanced unified constitutive model for simulating very high temperature fatigue-creep responses of Inconel 617 geared towards design and analysis of very high temperature gas cooled reactor components. The constitutive model has been extended for simulation of thermo-mechanical fatigue of Haynes 230 in order to improve design and analysis of combustor liner in jet engines. The model is being further improved by incorporating creep damage modeling features in order to simulate creep and fatigue interactions of modified Grade 91 steel for design applications to boiler header. The primary goal of Prof. Hassan's research group has been to improve inelastic analysis based design for enhancing life prediction of critical components. His projects have been funded by U.S. National Science Foundation, Department of Energy, Army Research Office, and industries related to aerospace, nuclear and fossil power, and offshore structures. He has performed research in cooperation with investigators in USA, France, Tunisia, India, and Turkey.
