Ultrasonic guided waves in solid media have become a critically important subject in
nondestructive testing and structural health monitoring, as new faster, more sensitive, and …

There is an increasing usefulness of exact three-dimensional analyses of elastic cylinders
and cylindrical shells in composite materials applications. Such analyses are considered as …

There are numerous interesting physical problems, in the fields of elasticity, acoustics and
electromagnetism etc., involving the propagation of waves in ducts or pipes. Often the …

The excitation of guided wave modes in generally anisotropic layers by finite sized strip
sources placed on the surfaces of the layer is examined. The general problem of arbitrarily …

This article is concerned with a flexible waveguide scattering problem arising in structural
acoustics. A mode-matching solution framework is explained from the perspective of …

The fundamental properties of guided waves in a laminate with any homogeneous boundary
conditions on its faces are considered. As shown, the waves satisfy orthogonality relations …

The Semi‐Analytic Finite Element method (SAFE) has been used to model the propagation
of ultrasonic waves guided (GW) by a structure and radiated at the guiding surface, a …

The properties of eigenwaves in laminated plates with anisotropy in a transforse directon
properties are studied. The most general form of the solutions, dispersion relations, power …

The ability to model wave propagation in circular cylindrical bars of finite length numerically
or analytically has many applications. In this thesis the capability of an explicit finite element …

The present thesis discusses the impact of external sound source in discontinuous
waveguide. The Mode-matching technique is applied to solve the governing boundary value …
