Tasnim Hassan is a faculty member in the Department of Civil, Construction, and Environmental Engineering at North Carolina State University (NCSU) since January 1995. At the undergraduate and graduate levels, he teaches courses related to mechanics, strength of materials, fatigue, fracture, and constitutive modeling (CE214, CE215, CE313, CE515, CE718). His experimental and analytical research includes understanding and modeling low-cycle fatigue failures of steel structures and welded joints, seismic performance of steel and concrete structures, sensor development, constitutive modeling of various steels, high-temperature alloys, concrete and polymeric materials. Currently, through a National Science Foundation project his research group (graduate students: Machel Morrison, Shahriar Quayyum, and Doug Schweizer, and undergrad student: P. Graham Pritchard) is conducting large scale experiments and simulations of steel building connections for validating and refining seismic performance enhancement techniques. Through two Department of Energy-Nuclear Engineering University Program and one Honeywell Aerospace projects his group (graduate students: Raasheduddin Ahmed, Paul Barrett, Yuanqing Wang, and Fengtao Bai) is making efforts in understanding very high temperature fatigue-creep failures of modern alloys. The experimental data and constitutive models to be developed through these projects will allow accurate life prediction of next generation nuclear power plant and jet engine components, and thereby safer and economical design of critical structural components. Two undergraduate students (Nick Smith and Brandon Mosiman) are currently working with him on pilot projects related to notch induced failure and concrete material. Over his tenure at NCSU, he has developed research cooperation with researchers from Civil Engineering, Nuclear Engineering, Mechanical and Aerospace Engineering, and Material Science and Engineering Departments at NCSU, Penn State University, University of Notre Dame, Oak Ridge National Laboratory, Idaho National Laboratory, INSA de Rouen, Ecole de Mines des Paris, Ecole Nationale d’Ingénieurs de Sfax Tunisia, and Yildiz Technical University in Turkey. He is affiliated with the American Society of Civil Engineers, American Society of Mechanical Engineers, American Society of Materials, Network for Earthquake Engineering Simulation, Inc., California Univ. for Research in Earthquake Engineering, American Institute of Steel Construction, American Academy of Mechanics, and American Society for Engineering Education. His research, education, and professional activities are geared toward understanding progressive failure of structures subjected to extreme loading conditions, developing constitutive models for more accurate prediction of structural failure, and finally developing techniques for enhancing fatigue life and/or performance of structures.
