The rectangular type of cross-section is chosen because of practical applications to describe the vibrations of some turbine blades. The analyses were conducted by applying an analytical model, but were verified using the finite element method.}, doi = {10.4467/2353737XCT.15.170.4375}, url = {https://ejournals.eu/en/journal/czasopismo-techniczne/article/possibility-of-existence-of-torsional-vibrations-of-beams-in-low-frequency-range} }
