Data and code for "First yield and out-of-plane stability of biaxially loaded perforated auxetic plates"

Research data and analysis code accompanying an article on the biaxial first-yield envelope of perforated auxetic plates and the component size at which out-of-plane buckling replaces first yield as the governing limit. Version 2.0.0 adds to version 1.0.0: (i) a second hole family, stadium slots, computed on the same lattice, the same ligament rule and the same solver as the elliptical family of version 1.0.0, twenty calibration and eight held-out geometries, used to test whether the scaling correlation depends on the hole outline; (ii) meshes carrying the full symmetry of the pattern for that family, on which the rhombic form of the locus is exact to the resolution of the computation; and (iii) the plate-bending homogenization, the geometric stiffness and the buckling eigenproblem, with their validations against closed-form plate results, from which the component-size criterion is obtained. Contents: code/homog, code/yield, code/rulecompliant, code/figures as in version 1.0.0; code/family2 the second hole family; code/stability the bending and buckling work; data/ the computed effective constants, loci, convergence and stability records; output/ the regenerated figures and tables.
