Neural-network surrogate predicts particle hydrodynamic responses accurately
—
in MechanicsWhat the study found A data-driven surrogate framework was developed to estimate hydrodynamic responses of rigid, non-spherical particles in Stokes flow, including the stresslet, angular velocity, and, for helicoidal particles, chiral thrust. The surrogate was trained on data generated by a validated boundary element method and was tested across random orientations and flow types. Why…
Chirality affects microcritical, not macrocritical, stability
—
in MechanicsAnalysis of periodic lattice metamaterials with rigid joints shows chirality affects microscale stability but not macroscale stability, enabling tailored critical mode activation.
Nonreciprocal stiffness and damping decouple wave control in elastic lattices
—
in MechanicsNonreciprocal elastic lattices with engineered damping enable decoupled control of wave amplification and propagation, allowing independent tuning of temporal growth and velocity characteristics.
