Soft‐Layered Composites with Wrinkling‐Activated Multi‐Linear Elastic Behavior, Stress Mitigation, and Enhanced Strain Energy Storage

open access: yesAdvanced Engineering Materials, EarlyView.
In this study, exciting new bi‐/multi‐linear elastic behavior of soft elastic composites that accompany the activation of wrinkling in the embedded interfacial layers is analyzed. The new features and performance of these composite materials, including dramatic enhancements in energy storage, can be tailored by the concentration of interfacial layers ...

Ceramic Keratoprostheses

open access: yesOphthalmology, 1980
This paper describes a new type of corneal prosthesis made of aluminum oxide ceramic. The implant consists of a retaining plate with a 3-mm central performation to which an optical cylinder is threaded. The cylinder also made of ceramic material, has a high refractive index and 60 diopters of power. Experimental study has shown that soft tissue adheres
