TL;DR: In this article, the authors developed a model that incorporates damage band evolution at three levels: (i) at the mechanism level, the damage mechanisms such as diffusive void growth and fatigue cracks, determine the damage growth rate; (ii) at an intermediate level, damage band is modeled as springs connecting undamaged materials, and the spring constants change as damage develops; and (iii) the damage band was modeled as an array of dislocations to satisfy equilibrium.

TL;DR: The poroviscosity theory as mentioned in this paper generalizes the classical theory of interdiffusion by decoupling the molecular processes for flow and diffusion, and treats the insertion of a molecular into a material element, accompanied by a change in volume, as a non-equilibrium process and is put on the same footing as the process of shear deformation by viscous flow.

TL;DR: In this paper, a thin layer of polymer coating, covering the islands and the substrate, was applied to increase the critical island size in a flexible electronic system, and the authors showed that this layer of polyethylene polysilicon (PPS) can significantly increase the island size.

TL;DR: In this paper, the effect of rate-dependent sliding on toughness was studied, where a crack through a matrix was considered and the fibers were intact and bridging the crack, and the composite was subject to a tensile load normal to the crack.

TL;DR: In this paper, the formation of creases using an elastic-plastic model with linear hardening was analyzed. And the degree of plasticity of the model by the ratio of the tangent modulus to elastic modulus, Et/E, was characterized.
