TL;DR: This work reports on a facile technique to harness fold-to-wrinkle transition and hierarchical wrinkling on soft material surfaces by regulating substrate stiffness and sputtering flux and could promote better understanding of the sputtering effect on the spontaneous pattern formation for soft materials.

TL;DR: In this article, size-dependent morphological characteristics of buckle-driven delaminations in large-scale brittle silicon nitride films in accompany with ridge cracking are reported, and the buckling morphologies fall into four distinct categories in a phase diagram.

TL;DR: In this article, a nonlinear solution based on the Foppl-von Karman (FvK) plate theory for buckle-delamination is derived by using a coordinate transformation technique in combination with perturbation series based on Koiter expansion.

TL;DR: In this paper, ridge cracking and low Poisson's ratio promote symmetric instability and favor bubble-like blisters while interface sliding and high Poisson ratio facilitate antisymmetric instability mode and result in telephone cord buckles.

TL;DR: Based on Foppl-von Karman (FvK) nonlinear plate theory, this paper derived an improved analytical solution for a better description of the cross-sectional profile of the straight-sided blister with straightsided ridge crack through considering the effect of hinge position caused by the ridge crack.
