Webinviscid and viscous flows. Following these results, it is presumed that the classical Rayleigh theorem is wrong which states that a necessary condition for inviscid flow instability is the existence of an inflection point on the velocity profile. In present study, we show rigorously the proof why Rayleigh theorem is wrong. WebThe fault-normal displacement of sub-Raleigh ruptures is charachertized by a prominent motion in the negative (downward) direction. The fault-normal displacement of supershear ruptures displays motion in the positive (upward) direction followed by a negative motion. It is also characterized by wedge features propagating in the far-field.
