Article: A frequency-independent second-order framework for the formulation of experimental fluidelastic forces using hidden flow variables
The importance of fluidelastic forces in flow-excited vibrations is crucial, in view of their damaging potential. Flow-coupling coefficients are often experimentally obtained from vibration experiments, performed within a limited experimental frequency range. For any given flow velocity, these coefficients are typically frequency-dependent, as amply documented in the literature since the seminal work of Tanaka and Takahara.
Damping reveals hidden dimensions in elastic metastructures through induced transparency
Dear Colleagues,
I invite you to read our recent study published in the Physical Review Applied: https://doi.org/10.1103/PhysRevApplied.21.054022
Abstract:
Localized plastic strain accumulation in shape memory ceramics under cyclic loading
The premature failure of shape memory ceramics (SMCs) under cyclic loading is a critical issue limiting their applications as actuators and thermal protection layers. Martensitic phase transformation (MPT), essential for superelasticity and shape memory functionalities in SMCs, induces localized plastic deformations due to phase expansion. In polycrystalline materials, the accumulation of localized plastic strain serves as the primary mechanism for fatigue crack initiation under cyclic loading.

Ph.D. Position in Mechatronics Engineering at Kent State University, Kent, OH
An immediate Ph.D. position is available in the Control, Automation, and Mechatronics (CAM) lab at Kent State University, Kent, OH. The program is housed within the College of Aeronautics and Engineering and focuses on Mechatronics Engineering. Ideal candidates will need to have completed their master’s degree in electrical, mechanical, or mechatronics engineering by the end of 202. They must possess a strong foundation in controls and machine learning, along with proficient programming skills in Python and MATLAB.
Tight bounds correlating peak absorption with Q-factor in composites and metallic clusters of particles.
Dear colleagues,
We invite you to read our article, which informs one about the extent to which resonances can be tuned in metamaterials. More precisely, our work provides tight bounds correlating the Quality-factor with peak absorption in dielectric metamaterials. The article is published in Applied Physics Letters and can be found here: https://doi.org/10.1063/5.0155092
