Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
We present a geometrically exact beam model for a cantilevered beam undergoing large-amplitude motions, motivated by recent wind-energy capture systems that exploit vortex-induced vibrations. The derivation of this model leads to a single nonlinear 2nd-order ordinary differential equation that appears similar to a Duffing oscillator with additional nonlinear acceleration terms. For prismatic configurations, the formulation is characterized by its linear natural frequency and a normalization constant of the shape-function. A brief parametric study is conducted to demonstrate the softening effects of the nonlinear acceleration terms. Continuation methods are used to construct the amplitude versus forcing frequency plots to capture the nonlinear response.
