Abstract: We describe here a method for determining the elastodynamic (P and SV waves) radiation characteristics of finite-size sources buried in a horizontally layered medium, having periodically corrugated ...

Abstract: The reflection and transmission characteristics of a grating of identical, circular elastic cylinders, arranged periodically in an elastic slab, are investigated. Use is made of a simple approach ...

Abstract: The plane wave scattering matrix theory is applied to formulate a T -matrix which characterizes the acoustic response of an infinite solid plate bounded by semi-infinite vacuum and fluid half ...

Abstract: A finite element eigenfunction method (FEEM) is formulated for elastic wave scattering by bounded three-dimensional axisymmetric regions (cavity, homogeneous, or inhomogeneous) for harmonic waves ...

Abstract: The scattering of waves by a flaw (cavity or inclusion) that is embedded in an elastic half space at a finite depth below the interface with a fluid half space is studied using the T-matrix ...

Abstract: This study is concerned with the T-matrix method to solve the scattering of SH-waves by an inclined surface-breaking void in a homogeneous elastic half space. Additional complications arising ...

Abstract: This paper presents a model reduction method and uncertainty modeling for the design of a low-order H∞ robust controller for suppression of smart panel vibration. A smart panel with collocated ...

Abstract: A state-space representation of a dynamic system for one-dimensional sound reflection and transmission is developed. The state-space modeling is the first step for future development of an active ...

Abstract: A hybrid finite element eigenmode—Floquet mode representation is formulated and numerically implemented to study the performance of composite transducers subject to fluid loading. The periodic ...
