Faraday waves in soft elastic solids

WebFeb 27, 2024 · Typical solids have Poisson’s ratios of \(\nu \approx 0.05\) if hard and \(\nu = 0.25\) if soft. The stiffness of elastic solids in terms of the elastic moduli of solids can be complicated due to the geometry and composition of solid bodies. Often it is more convenient to express the stiffness in terms of the spring constant \(\kappa \) where WebMay 27, 2024 · Faraday waves, or parametrically excited surface waves , have been well characterized and understood because of a large body of laboratory experiments and numerical simulations. At low excitation amplitude, these nonlinearly generated waves form stable patterns ( 2 – 5 ), and as the forcing is increased, the patterns become unstable ...
