Elastic Wave Propagation in Structures and Materials

Elastic Wave Propagation in Structures and Materials initiates with fundamentals covering spectral analysis, computation of wave parameters, wave propagation in 1-D isotropic waveguides, wave dispersion in 2-D waveguides. Wave propagation in different media including non-local elasticity models is addressed backed by codes and homework problems.

Prof. Gopalakrishnan received his Master's Degree in Engineering Mechanics from Indian Institute of Technology, Madras, Chennai and Ph.D from School of Aeronautics and Astronautics from Purdue University, USA in the year December 1992. After his Ph.D., he was a Postdoctoral Fellow in the department of Mechanical Engineering at Georgia Institute of Technology. In the year November 1997, he joined the Department of Aerospace Engineering at Indian Institute of Science Bangalore, where currently he is a senior Professor. His main areas of interest are Wave Propagation in complex media, Computational Mechanics, Smart Structures, and Structural Health Monitoring. He has publisher 218 refereed international journal publications and has authored 9 textbooks and monographs and has an h-index of 50 in Google scholar. He is in the editorial board of 6 international journals and is the Associate editor for Smart Materials and Structures and Structural Health Monitoring international journals. Prof. Gopalakrishnan is decorated with many awards and honors, which include, International Structural Health Monitoring person of the year awards 2016 instituted by SAGE Publications, Fellow of Indian National Academy of Engineering, Fellow of Indian Academy of Sciences, Associate Fellows AIAA, Distinguished Alumnus Award, Indian Institute of Technology, Madras, Chennai, Satish Dhawan Young Scientist Award by Government of Karnataka, Biren Roy Trust award of Aeronautical society of India, Alumni Award of excellence in research at IISc and the Royal Academy of Engineering, UK Distinguished visiting Fellowship.
