About awarded research
Hiroaki Deguchi, Kei Matsushima, Takayuki Yamada, Decomposition of Displacement Fields into Scalar Potentials and Their Orthogonality in Spherical Elastic Media, The 37th Computational Mechanics Conference, The Japan Society of Mechanical Engineers, 18-20th October 2024, Sendai, OS-0114.
Recently, wave phenomena peculiar to non-Hermitian systems, where the energy of the system is not conserved, have attracted significant attention. This study demonstrated that one such phenomenon—the simultaneous degeneracy of eigenvalues and eigenmodes (exceptional points)—can also occur in three-dimensional open elastic fields. In particular, this presentation focused on the decomposition of displacement fields into scalar potentials and their orthogonality in spherical elastic media. Our results suggest that non-Hermitian physics can be applied not only to quantum mechanical systems but also to mechanical systems involving acoustic and elastic fields.
Your impression & future plan
I have always been fascinated by the theories behind structural forms, which has motivated my research. I am truly honored that my work has been recognized in this way. At the same time, I would like to express my sincere gratitude to everyone who has supported me. Moving forward, I would like to continue to work on designing structures through theoretical and numerical approaches.
