Droplet, EarlyView.Curved hydrophobic mesh surfaces enable stable release of large droplets exceeding the capillary length. By tuning surface curvature, porosity, and acceleration, oscillatory breakup is suppressed, producing near‐spherical droplets ideal for high‐precision fluid applications and multiphase flow control.

Non‐monotonic jet pinch‐off induced by droplet impact on immiscible liquids
Droplet, EarlyView.The graphical abstract shows the evolution of the central jet following droplet impact and summarizes the non‐monotonic dependence of the critical Weber number on the dimensionless film thickness and Ohnesorge number. Abstract Droplet impact on immiscible liquids can generate a central jet whose pinch‐off behavior plays a crucial role in many advanced ...

PROPAGATION OF RAYLEIGH WAVE IN SOLIDS WITH FILLET TRANSITIONS
Приборы и методы измерений, 2015 New distinctive features of the elastic wave excitation and propagation when the Rayleigh wave probes used have been discussed. It was principally shown that such probes can be used not only to find surface defects but to find vertically oriented defects

On the existence of weakly nonlocal Rayleigh waves with impedance boundary condition
Archives of MechanicsIn this paper, the existence of Rayleigh waves propagating in weakly nonlocal incompressible isotropic elastic half-spaces subject to the tangential impedance boundary condition (TIBC) (at the surface of half-spaces, the tangential stress is proportional

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Rocking podium isolation systems have gained significant research interest as a method of limiting seismic demands on superstructures and eliminating residual post‐earthquake drifts through self‐centring behaviour. However, while numerous models of varying complexity, including analytical, phenomenological, and physical formulations, have been

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Steel Concentrically Braced Frames (CBFs) are widely used in seismic regions, with chevron and split‐X configurations commonly adopted for their structural efficiency and architectural flexibility. Although extensive research has been carried out on these systems, the effectiveness of the formulations available in the literature for estimating

Analysis of Rayleigh wave interactions for surface crack characterization [PDF]
, 2012 Electromagnetic acoustic transducers (EMATs) have been used in pitch-catch mode for a better characterization of surface cracks in metals. The system, which combines the measurement of Rayleigh wave velocity in the in-plane and out-of-plane directions ...

Complex Versus Parsimonious Site‐Based Stochastic Ground Motion Models: Which One Is Better?
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Stochastic ground motion models (GMMs) provide a probabilistic representation of seismic input and are increasingly important for uncertainty quantification (UQ) in earthquake engineering. This study focuses on site‐based stochastic GMMs, which learn the statistical features of selected datasets of seismic records and generate statistically ...
