Professor Gopalakrishnan has made seminal contribution in the areas of wave propagation in complex mediums and Structural Health Monitoring. Wave propagation is a fertile and wellresearched area where Prof. Gopalakrishnan has made a mark both nationally and internationally through his seminal contributions. He has practically looked at wave propagation in most of the complex mediums such as metals, anisotropic materials such as laminated composites, functionally graded materials, carbon nanotubes and nanotubes reinforced nano composites structures, periodic structures such as hexagonal lattices, sandwich structures, fluids and electromagnetics. He has successfully solved many of these wave propagation problems through a unique combination of sound mathematical skills coupled with innovative and original ideas. His notable contribution is the invention of a new numerical method called Spectral Finite Element Method (SFEM), which has already become a tool to solve many wave propagation problems in complex media involving very high frequency input. The reason for SFEM popularity is that it can solve high frequency content problem at a fraction of a cost compared to many established analysis tools such as finite element method. In addition, SFEM makes the solution of inverse problems such as source or system identification simple and straightforward, which is not the case with conventional analysis tools. This has opened up the possibility of solving many difficult inverse problems such as load monitoring in aircrafts, crack detection and quantification in structures and systems, earthquake/Tsunami modeling, new material design for impact mitigation etc.
His research efforts are primarily responsible for bringing out clarity and complete understanding of many wave based phenomena in complex media. His contributions can be summarized as follows:
Prof. Gopalakrishnan has extensively published his work on many top rated international journals of very high impact factor. He has spread his work by publishing in over 50 different journals. He has a total of 164 journal papers, 5 graduate level books, two undergraduate books, 9 book chapters, 88 international conference papers and 13 national conference papers
