A highly stretched hyperelastic shell exhibits a coupling behavior of local wrinkling and global bending within the stability boundary, and curvature resists and can even suppress surface wrinkles beyond a critical threshold. Here, we report a novel phenomenon that smooth surface maintains upon stretching a soft shell, while wrinkles emerge upon unloading, which implies a nonlinear interplay between curvature and Mullins (stress softening and residual strain) effects in the entire loading-unloading cycle.

Stimulus activated structures that deform from a reference to target configurations are used in various fields such as soft robotics, smart materials, and actuators.  In this work we introduce a framework that captures the non-linear response of multi-layer polymeric beams subjected to thermo-mechanical loading. We show that the exploitation of the glass transition temperature can lead to a wide variety of interesting responses. Our findings provide guideline for an efficient design of shape-morphing structures capable of polymorphism.

Following the approach of Griffith, Sneddon and Muskhelishvili calculated the pressure of tear propagation in elastic media. Gent and Lewandowski collected these works and using Hencky's approximation of membrane deformation, introduced a collection of relationships on the debonding of films from substrates by pressure (left panel).

Shape-changing materials with precisely programmable configurations, each having its own functional regime, provide a wide range of applications in engineering and biomedical fields. Polymers with dynamic reversible covalent/non-covalent bonding feature the potential of having remarkable plasticity, which endows them with the capability of undergoing significant and sophisticated shape changes. Here we report a facile method to build an interpenetrating network (IPN) structure with plastic deformation and shape memory properties.
