Nonlinear fractional waves at elastic interfaces

Year: 2017

Type: article

Abstract: A nonlinear fractional wave equation for 2D sound waves at interfaces is derived from first principles. Numerical solutions of the equation reproduce experimental key features, namely an abrupt increase in range accompanied by a slight increase in wave velocity at a threshold excitation amplitude.
