Criteria for determining buckling modes of interconnect.

Mode #	k^mode_side	k^mode_mid	Description
I (◆)	0.5	0.5	Antisymmetric buckling
II (■)	0.5 or 1	1	Symmetric buckling without wrinkles in the side segments and global buckling in the mid segment
III (●)	0.5 or 1	1.5	Symmetric buckling without wrinkles in the side segments and transitional buckling in the mid segment
IV (★)	0.5 or 1	2, 3, …	Symmetric buckling without wrinkles in the side segments and local wrinkles in the mid segments
V (☖)	1.5, 2, 3, …	2, 3, …	Symmetric buckling with wrinkles in the side segments
