Research and Teaching Interests

Dr. Venkataraman's expertise is in the area of structural optimization. His recent work has investigated progressive failure predictability of composite laminates. He has published papers on identification of factors affecting failure predictability and use of surrogate measures to improve robustness and failure predictability (Venkataraman and Salas, 2007), use of structural fuses to control failure and improve robustness and failure predictability (Salas and Venkataraman, 2007), investigation of effect of model uncertainties in progressive failure predictability (Salas and Venkataraman, 2006), and effect of load redistributions and competing failures in progressive failure of redundant truss structures (Marhadi and Venkataraman, 2006).

His previous work has investigated optimal design of shell structures having initial geometric imperfections (Venkataraman et al, 2003 , Lamberti et al 2003 ), use of approximate surrogate models for efficient design space exploration and reliability based design optimization (Venkataraman, S. 2005 ; Qu et al. 2003 ), biomimetic design of holes for reduced stress concentration (Venkataraman et al, 2003 and Huang et al. 2003 ), analysis of structures with functionally graded materials Venkataraman and Sankar 2003 ), design of thermal protection systems with functionally graded metal foams for thermal insulations in launch vehicle thermal protection systems (Venkataraman et al, 2004 , Zhu et al, 2004 ), developing efficient global-local design optimization methods for aircraft structures and calculating confidence intervals for reliability estimates based on the uncertainty in the statistical variables (Venkataraman et al, 2006, 2007).
