Experimental data & graphs
Inspect how publicly archived graph nodes move through a corrugated-board compression sequence. The interactive view stays in image pixels and preserves missing observations instead of converting, smoothing or reconstructing unavailable source data.

Article evidence audit
The CC BY 4.0 article records experimental compression videos converted into image-derived graphs. The paper cases are kept separate from the exact public Exp3 snapshot above and from the independent truss benchmark below.

Vertical and horizontal displacement clustering formed four periodic node subgroups. Three of four load peaks were predicted from group motion; peaks A and B appeared less than 100 µm of deformation before the measured peaks.
Reported buckling rule: Start at the first flute-segment angle sign change; end at 90% of segments.

The same four subgroup construction was recovered, while the horizontal motion direction and sequence differed from Experiment 1. The buckling range surrounded the highest measured peak.
Reported buckling rule: Start at the first flute-segment angle sign change; end at 80% of segments.
The interactive tracker on this page is an exact public Exp3 pixel-coordinate snapshot from the repository, not either article experiment replay. It contains no video, graph edges, force curve or physical calibration. The separate truss lab is an independent reduced benchmark, not an article result or FEM simulation.

Paper link and evidence boundary
The CC BY 4.0 TechRxiv v1, posted 3 August 2025 preprint uses frame-specific image-derived graphs, direction-dependent members and quasi-static loading to report axial force, shear, bending moment and deformation for four selected compression states. Its public source records EMD = 2.5 GPa, EZD = EMD/200, board width 25 mm and sample length 100 mm.
C1 · Experiment 1 Peak A
335 N · 134 kPa · frame 48
C2 · Experiment 1 Peak D
619 N · 245 kPa · frame 121
C3 · Experiment 2 Peak A
516 N · 206 kPa · frame 55
C4 · Experiment 2 Peak C
711 N · 284 kPa · frame 129
These four values are cited paper evidence, not outputs of the reduced benchmark above. ProjectHub still lacks a permission-cleared frame topology/member-property/load archive needed to reproduce the paper solver. The current public Graph-CB files remain experimental pixel tracking and are not relabelled as simulation.
CC BY 4.0 preprint · TechRxiv v1The public pipeline exports frame-0 coordinates as row_px and col_px. It records dx_px = new_col − first_pre_col, dy_px = new_row − first_pre_row and their Euclidean magnitude for each node/frame observation.
