Figures 3 and4 show that the beam with the smallest roughness can obtain the highest tuning ratio from the original resonant frequency.
(1) A new IGA beam element is developed by integrating the displacement field of the element, which is approximated by the NURBS basis, with the internal work formula of Euler-Bernoulli beam theory with the small deformation and elastic assumptions.

The considered beam is treated as a Bernoulli Euler beam in accordance with the small bending theory.
Additionally, for a beam or column with the small shear-span to depth ratio, since the arch mechanism occurs after the diagonal shear cracking, Eq. (9), which is proposed based on the shear-compression failure mode, is recommended to evaluate the ultimate shear strength of concrete, v dd.
Our results indicate that with the propagation distance increasing long enough in far field area, the initial profile of FPGM laser beams gradually disappears, and finally the profile converts into Gauss-like beam with several small petals.
From the experiments, it is important to notice that deep beam with relatively small span-to-depth ratio under axial load shows early failure due to concrete crushing, which cannot be directly applied to widely known design method for deep beam, strut-to-tie model.
In front of the charge breeder, an RFQ cooler-buncher will be used to deliver a bunched beam with small emittance to the EBIS charge breeder.
Electron beam with a small low energy cut off is thermalized faster than that with a high low energy cut off.
