Random Vibration of Space Shuttle Weather Protection Systems
Shock and Vibration, 1995 The article deals with random vibrations of the space shuttle weather protection systems. The excitation model represents a fit to the measured experimental data. The cross-spectral density is given as a convex combination of three exponential functions.

Human‐Induced Vibration of Long‐Span Multi‐Layer Composite Beams—Analytical Calculation Method
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 106, Issue 8, August 2026.ABSTRACT The finite element method (FEM) provides a general framework for analyzing virtually all types of structures under various loading conditions. Nevertheless, in certain situations, designers may identify that the structural system exhibits predominantly beam‐like behavior, allowing the use of analytical theories.

Non-uniform Euler-Bernoulli beams´ natural frequencies
Ingeniería e Investigación, 2011 This paper has studied the problem of natural frequencies for Euler-Bernoulli beams having non-uniform cross-section. The numerically-obtained solutions were compared to asymptotic solutions obtained by the Wentzel-Kramers-Brillouin (WKB) method. It was established that WKB formula precision was higher than 3% for high frequencies (≥ 4 mode).
