Webb26 nov. 2024 · The reflection phenomenon of attenuated waves is considered at the stress-free boundary of an initially stressed fiber-reinforced medium. An arbitrary arrangement of fibers is taken into account. The slowness vectors of reflected waves are associated with the incident wave slowness vector by generalized Snell’s law. WebbThe wave inhomogeneity may be described by means of field measurement and/or numerical simulations. Both approaches face complications when the resolution is much refined. It is thus important to examine the effect of the resolution related to the modelling of inhomogeneous waves on the global structural responses.
