Joint identification in structural waveguides using wave reflection and transmission coefficients [PDF]

open access: yes, 2007
The dynamic modelling of one-dimensional jointed structures is relevant to many engineering applications, such as pipe systems and beam networks in constructions. Currently available techniques are undermined by inadequate ability to model the joints and

Reflection And Heating Coefficients In Southern Ontario [PDF]

open access: yes, 1968
Reflection and heating coefficients were measured during the 3 month summer season at Simcoe, southern Ontario. Contrasting agricultural surfaces and atmospheric conditions were used to analyse their effect on the reflection and heating coefficients ...

Reflection of P1-wave incident obliquely at the free surface of a fluid-saturated half-space: a comprehensive study via the model of soil mechanics

open access: yesFrontiers in Physics
IntroductionElastic wave propagation in fluid-saturated porous media is of great significance in various fields. Based on the soil mechanics model of a two-phase medium, the reflection problem of an obliquely incident plane P1-wave at the free surface is
