Internal wave focusing by annular forcing
A linear theory is proposed for the focusing of internal waves generated by the oscillations of a horizontal annulus that is slender, namely of large aspect ratio, but otherwise arbitrary. The theory exploits the separation of scales and is applied to two configurations: a circular torus, and circular Gaussian topography at the ocean bottom. Both complete and partial annuli are considered. Focu...
متن کاملInternal Stress Plasticity Due to Chemical Stresses
Internal stress plasticity occurs when a small external stress biases internal mismatch strains produced by, e.g., phase transformation or thermal expansion mismatch. At small applied stresses, this deformation mechanism is characterized by a deformation rate which is proportional to the applied stress and is higher than for conventional creep mechanisms. In this work, we demonstrate the operat...
متن کاملStress relaxation due to chain fractures in transient polymer networks
" Aspects of a network model for concentrated dispersions are applied to polymer networks. It is shown how network deformation caused by network fracture affects the macroscopic stress.
متن کاملInternal stress wave measurements in solids subjected to lithotripter pulses.
Semiconductor strain gauges were used to measure the internal strain along the axes of spherical and disk plaster specimens when subjected to lithotripter shock pulses. The pulses were produced by one of two lithotripters. The first source generates spherically diverging shock waves of peak pressure approximately 1 MPa at the surface of the specimen. For this source, the incident and first refl...
متن کاملObservation of sound focusing and defocusing due to propagating nonlinear internal waves.
Fluctuations of the low frequency sound field in the presence of an internal solitary wave packet during the Shallow Water '06 experiment are analyzed. Acoustic, environmental, and on-board ship radar image data were collected simultaneously before, during, and after a strong internal solitary wave packet passed through the acoustic track. Preliminary analysis of the acoustic wave temporal inte...
