abstract = {This paper has studied the problem of natural frequencies
for Euler-Bernoulli beams having non-uniform crosssection. The numerically-obtained solutions were compared to asymptotic solutions obtained by the WentzelKramers-Brillouin (WKB) method. It was established that
WKB formula precision was higher than 3% for high frequencies (≥ 4 mode).},
