Analysis and Experimental Investigation of Wave Propagation and Energy Transfer in Mechanical Rotator Metamaterials
… research by incorporating geometric or material nonlinearity, resulting in a wide range of amplitude-dependent wave phenomena, such as dispersion shifting, frequency conversion, and non-reciprocal energy transfer. This dissertation explores these diverse phenomena and interactions in nonlinear …

Engineering, characterization, identification and reduced order modeling of systems with softening nonlinearities
… modeling and characterization of a new type of softening-hardening nonlinear springs. This can be successfully employed as vibration mitigation devices owning to a rather unique tunability feature. For instance, being capable of softening or hardening behavior, i.e., possessing decreasing or …
