Abstract

Delamination  is a severe mode of damage in composite and sandwich structures, which can  significantly affect their response and eventually lead to catastrophic failure.  This study is the first attempt to develop an electromechanically coupled  efficient layerwise finite element (FE) model for the analysis of smart  piezoelectric multilayered shells of general shapes featuring delaminations and  debonding of sensors and actuators. For the laminate mechanics, an efficient  coupled zigzag theory developed by the speaker’s group is employed. The active  vibration control of laminated plates/shells with piezoelectric sensor and  actuator patches is also studied for delaminated structures with or without  actuator/sensor debonding.

Dr. Santosh  Kapuria is a Professor  of Applied Mechanics at Indian Institute of Technology Delhi, and currently the  Director of CSIR-Structural Engineering Research Centre, Chennai, India. He  received his PhD in Applied Mechanics in 1997 from Indian Institute Technology  Delhi, M.E. in Structural Eng from Indian Institute of Science, Bangalore, and  B.E. from Jadavpur University, Kolkata. Prof. Kapuria's research interests are  mechanics of smart (multifunctional) structures, computational structural  mechanics, active vibration control, structural health monitoring, and  biomechanics. He has published 130 papers in top quality international journals.  He has been a Humboldt Research Fellow at Technische Universität Darmstadt,  Germany and a Fulbright Senior Research Fellow in Stanford University, USA. He  is an elected Fellow of the Indian National Academy of Engineering, Indian  National Science Academy, Indian Academy of Sciences and National Academy of  Sciences, India. Prof Kapuria has also received the prestigious J. C. Bose  National Fellowship. He is a member of the Editorial Board of Journal of  Thermal Stresses (Taylor & Francis), and has been the guest editor of  ACTA MECHANICA (Springer) for a special issue on mechanics of  functional materials and structures.
