Numerical methods in wave propagation in periodic structures
Numerical methods in wave propagation in periodic structures
This work describes a computer oriented study in wave
propagation in periodic structures.
A simple introduction is first provided to review the
concept of propagation constant and to lay down the basic terminology and ideas
for subsequent development.
A general matrix theory of free wave propagation in general
linear periodic structures is constructed. A general equation for the propagation
constant is derived.
Stringer-stiffened plates and ring-stiffened cylinders
undergoing only axi-symmetric motion are analysed by using this general theory.
The effect of coupling between transverse and torsional movement of a support
(stringer) is considered.
Numerical methods for the computation of the field transfer
matrix are analysed and modifications introduced, where appropriate, to
Increase accuracy and speed up computation time.
Free wave propagation in stringer-stiffened cylindrical
shells and ring-stiffened cylinders undergoing general vibration motion is
analysed by using the general method. The frequency dependence of the
propagation constant is discussed.
The concept of complex wave component is
introduced and used in the construction of a general matrix wave theory of the
response of finite and infinite periodic systems to concentrated harmonic
forces. This theory is applied to finite and infinite stringer-stiffened plates
and shells.
A general theory of the response of finite and infinite
systems to a convected harmonic pressure field is derived and applied to
stringer stiffened plates and shells.

Abstract
This work describes a computer oriented study in wave
propagation in periodic structures.
A simple introduction is first provided to review the
concept of propagation constant and to lay down the basic terminology and ideas
for subsequent development.
A general matrix theory of free wave propagation in general
linear periodic structures is constructed. A general equation for the propagation
constant is derived.
Stringer-stiffened plates and ring-stiffened cylinders
undergoing only axi-symmetric motion are analysed by using this general theory.
The effect of coupling between transverse and torsional movement of a support
(stringer) is considered.
Numerical methods for the computation of the field transfer
matrix are analysed and modifications introduced, where appropriate, to
Increase accuracy and speed up computation time.
Free wave propagation in stringer-stiffened cylindrical
shells and ring-stiffened cylinders undergoing general vibration motion is
analysed by using the general method. The frequency dependence of the
propagation constant is discussed.
The concept of complex wave component is
introduced and used in the construction of a general matrix wave theory of the
response of finite and infinite periodic systems to concentrated harmonic
forces. This theory is applied to finite and infinite stringer-stiffened plates
and shells.
A general theory of the response of finite and infinite
systems to a convected harmonic pressure field is derived and applied to
