Gyanender Singh

Research Scientist


Research Interests:

Dr. Singh has expertise in determining the thermo-mechanical behavior of materials under complex physical conditions with the aim of predicting the performance of structures and components under operation and design optimization.  Besides, he holds significant experience in mechanical testing of ceramic composites, monoliths, graphite and HDPE, and also uses non-destructive techniques for evaluating the mechanical properties of these materials. His doctoral studies were focused on the development of an explicit-crack-modeling based approach for performing the structural integrity assessment of brittle and quasi-brittle materials. Prior to doctoral work he performed research for characterizing the mechanical degradation of polymer materials under exposure to oxidizing environment.
