Tensile test samples were prepared in the x-direction (sheet rolling direction) and the z-direction (in sheet plane direction that is transverse to the rolling direction), and compression test samples were prepared in the y-direction (sheet thickness direction).
The arrangement of β-strands within β-sheets can be antiparallel, β-sheet relative orientation (face-to-face or face-to-back) and β-sheet direction (up or down).
In addition, in this case, the Poisson effect occurs in the thickness direction because the plastic sheet was originally fabricated by stretching in the plane direction; therefore, the sheet shrinks in the in-plane direction and expands in the normal direction to approach the original dimensions.
In situ tensile tests on PU foams reveal that the initial main elongation axis of the cells evolves from the foam sheet normal direction to the rolling direction of the coils.
In this paper, we examine the case of (alpha _2=0.01) where the resistive disturbance is slightly fluctuated only by 1%% in z-direction which is the sheet current direction.
Figure 1a shows that 2D fast reconnection process generates a 2D plasmoid at (T=72), where the (B_y) contour map is almost uniform in z-direction, i.e., the sheet current direction.
With a little prompting, they recreate a pattern from a nearby instruction sheet, following directions and placing balls in certain spaces on the grid.
The initial small resistive disturbance is almost 2D on the plane perpendicular to the sheet current direction but includes weak fluctuations (perturbations) in the sheet current direction.
Rather, since the initial resistive disturbance employed in his 3D studies was assumed to be strongly localized in the sheet current direction, the resulting fast reconnection process was consequently localized in the sheet current direction.
Our study shown here suggests that BBFs generated by the 3D fast reconnection process can be strongly localized in the sheet current direction without any distinct externally driven mechanism to localize the reconnection region in the sheet current direction.
