a Polar distribution of cell edge vectors in a stable state. b Polar distribution of cell edge vectors in an unstable state. c Edge length density distribution at different instability. Panels (a–c) were generated using p0 = 3.72. d The stress-strain curve is overlaid with C(l)-strain curve at different l. The green box highlights the trace with a high correlation between σ and C(l). e The correlation between tissue stress and the cumulative edge length distribution Rσ,C(l) suggests a robust critical normalized edge length l*. Inset: The correlation between tissue stress and the proportion of edges at different orientations Rσ,F(ω). f Color-plot of the correlation RC,F between edges length distribution and edges orientation distribution. The black-dashed circle indicates the region where the correlation is maximized, from which l* could be determined. Source data are provided in a Source Data file.
