As a specialist in structural dynamics, in the past twenty years he has worked in wave-based approaches such as the spectral element method, power flow methods, wave propagation methods, and the wave finite element method.
He has supervised many graduate research theses on these topics, both concerning semi analytical and numerical methods. In the past decade he has focused his research on periodic structures and their unique behavior (e.g., band gaps and topological modes).He has supervised many graduate research theses on these topics, both concerning semi analytical and numerical methods.

This project will gather the efforts of the most active researchers in the state of São Paulo in periodic structures such as phononic crystals and metamaterials.
As a Co-PI, Prof. Arruda is responsible for the Work Package on Quasi Periodic Structures. The approach is two-fold. The effects of variability and randomness in these wave propagation properties are investigated as will some particular effects of quasi-periodic structures, e.g. topological modes. Prof Arruda coordinates the efforts of experienced and young researchers in the state of São Paulo, Brasília (UnB), France (INSA Centre Val de Loire), graduate and undergraduate students and foreign collaborators aiming at developing new analytical and numerical tools for the analysis and design of quasi periodic structures, performing experiments to validate the developed models, and searching for industrial applications, e.g., NVH, SHM, and NDE with guided elastic waves.
