Vibration of Beam Structures

1991
We treat the dynamics of beams in a manner similar to that for rods. The sequence of analysis followed is: derive the governing differential equations, use spectral analysis to obtain general solutions, obtain an exact matrix formulation, obtain an approximate matrix formulation.

Fault identification in beam structures

Journal of the Franklin Institute, 1992
A methodology based on the measurement of the natural frequencies of the structural system is developed for identification of the magnitude and location of the material defects and/or cracks. The numerical procedure is based on the matrix-transfer technique in which the dynamic characteristics of the system are related from one end to the other end via

Structural optimization using beam elements

AIAA Journal, 1988
Techniques for handling beam elements in structural optimization are investigated. The complexities of evaluating the geometrical properties of a section, stress recovery, and design-variable selection are successfully handled by the concept of an element library, use of equivalent stress, and separation of sensitivity variables and design variables ...
