Abstract: The modal element method for acoustic scattering from a two-dimensional body is presented. The body may be acoustically soft (absorbing) or hard (reflecting). The infinite computational region ...

Abstract: An explicit finite difference iteration scheme is developed to study harmonic sound propagation in ducts. To reduce storage requirements for large 3D problems, the time dependent potential form ...

Abstract: A general methodology is constructed for the fundamental solution of an arbitrarily oriented crack embedded in an infinite nonhomogeneous plate in which the shear modulus varies exponentially ...

Abstract: In Part 1 of this work, an analytical model was developed for the fundamental solution for a crack embedded in an infinite nonhomogeneous plate. This fundamental solution is used here to ...
