Goldstein et al. [1] concluded that the film cooling performance can be enhanced by using shaped channels.
Thole et al. [5] explained that these vortices are formed by turning of secondary flow due to free stream.
Gao et al. [12] analyzed the film cooling effectiveness of a HP turbine blade on sides.
Note that this work is inspired by a research that was done and published by the researchers: Hasn Nasir et al. [25], Kohli et al. [26].

Doyle [12] and Krawczuk et al [19] analyzed wave propagation in a rod and beam with a vertical fatigue crack, in which the crack was modeled as a massless spring.
IM7/5250-4 composite is used as the material of the beam(EL=168GPa, ET=9.31GPa, GLT=5.17GPa, GTT=3.45GPa, νLT=0.33, νTT=0.33, ρ=1610kg/m3).

Simoneau et al. discussed the grain boundary effect in medium carbon steels, and he found the different grain deformation in cutting chip [7].
Lee et al. discussed material induced vibration, which is caused by the changing crystallography of the material substrate [8, 9].

Keywords: Composite materials, Glass/Epoxy woven fabric plates, Delamination, Crater on impacted face, Impact fatigue loading.
The detail on this machine can be accessed in a previous work of Azouaoui et al. [7].
The depth is measured by a comparator with an accuracy of 1/100 mm and the surface (SC) is determined by the relationships (Eq. 3 and Eq. 4) given by Azouaoui et al. [8]

At the same speed and time, the crystallite size of T2 is lower (21.4 nm) than Silva et al. [20] results (36.9 nm) which used precursors from CaH(PO)4 and Ca(OH)2.
In addition, the crystallite size (21 nm) obtained at M3 is higher compared to Silva et al. [20] (14.3 nm) with Ca(CO)3 and CaH(PO)4 as precursors and lower than crystallite size obtained from CaCO3 and (HN4)H2PO4 precursors (35.5 nm).

Some authors have successfully used this technique to reduce the pore volume of Al-12Si alloy by several percent and halved the average size of individual pores by drying the powder at 100° C for 1 h before the printing process [7].
