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, 1992A 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, 1988Techniques 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 ...

Structured beams in laser refractography
Journal of Communications Technology and Electronics, 2009The main types of structured laser beams obtained using diffractive optical elements are presented. A new information and measuring technique—the laser refractography based on the application of structured radiation—is proposed for the quantitative diagnostics of inhomogeneous media.

Spin Structure with Lepton Beams
2005The next several years should see a significant increase in the amount of data. Precise semi-inclusive data is expected from HERMES. CEBAF 39 has an extensive program of measurements planned at large x and low Q 2. The new CERN proposal COMPASS 32 will extend the high Q 2 data and provide information on semi-inclusive charm production, that may shed ...
