PhD on reconfigurable Elastic Metamaterials at Politecnico di Torino, Italy

id="offer-description" class="ecl-u-type-heading-2 ecl-u-mt-none ecl-u-mb-l">Offer Description This PhD project will investigate wave propagation in architected media whose dynamic response can be modified through external stimuli, deformation, flows or intrinsic nonlinearities. The general objective is to understand how reconfigurability and nonlinear effects can be used to control dispersion, localization, transmission, mode conversion, and energy transport in architected media. The research will address one or more topics including tunable band gaps, topological edge or interface states, reconfigurable waveguides, space–time modulation, non-reciprocal propagation, frequency conversion, and amplitude-dependent localization. Tunability may be obtained through prestress or finite deformation, geometrical instabilities, active or responsive materials, flows or other suitable physical mechanisms. A central aim will be to identify the physical mechanisms governing transitions between different wave-propagation regimes and to determine their robustness with respect to damping, disorder, imperfections, and finite-amplitude excitation. Particular attention may be devoted to the interaction between nonlinear dynamics and topological or localization phenomena, including switching, modal coupling, hysteresis, and dynamically induced changes in the wave spectrum. The work will combine analytical and reduced-order modelling, numerical simulations, and experimental validation. Approaches
