Hierarchical assembly of self-healing adhesive proteins creates strong and robust structural and interfacial materials, but understanding of the molecular design and structure-property relationships of structural proteins remains unclear. Elucidating this relationship would allow rational design of next generation genetically engineered self-healing structural proteins. Here we report a general...

We describe the design and implementation of an agent based simulation for a smart grid. The design supports the evaluation of procedures for self healing. The main design goal is to support the testing and comparing of alternative decision models that can specify grid-management actions that can be applied in scenarios that call for self healing. We first describe the agent and decision model ...

The four key objective properties of a system that are required for it to qualify as “autonomic” are now wellaccepted––self-configuring, self-healing, self-protecting, and self-optimizing––together with the attribute properties––viz. self-aware, environment-aware, selfmonitoring and self-adjusting. This paper describes these self-* properties as exhibited in NASA missions, and in particular wit...

Smart Cyber-Physical Systems (CPSs) are autonomic systems capable of making decisions at runtime by themselves. These systems are complex in nature and typically operate in highly unpredictable and uncertain environments. One key autonomic capability of such systems is to recover from failures in an autonomic manner, referred to as self-healing. Due to the wide range of applications of smart CP...

Self-healing is a capacity observed in most biological systems in which the healing processes are autonomously triggered after the damage. Inspired by this natural behavior, researchers believed that a synthetic material possessing similar self-recovery capability could also be developed. Albeit various intrinsic self-healing systems have been developed over the past few decades, restriction on...

Formation of microcracks is a critical problem in polymers and polymer composites during their service in structural applications. Development and coalescence of microcracks would bring about catastrophic failure of the materials and then reduce their lifetimes. Therefore, early sensing, diagnosis and repair of microcracks become necessary for removing the latent perils. In this context, the ma...

Due to its low tensile strength and the presence of defects brought on by improper construction methods or other factors, cracks in concrete are practically inevitable. For reinforced-concrete structures, even if do not necessarily increase risk collapse, they unquestionably hinder aspects such as service life. Self-healing cementitious materials have been developed because growing concern for ...

In this study autonomic self-healing of impact damage in composite materials is shown using a microencapsulated healing agent. The components for self-healing, urea–formaldehyde microcapsules containing dicyclopentadiene (DCPD) liquid healing agent and paraffin wax microspheres containing 10 wt% Grubbs’ catalyst, have been successfully incorporated in a woven S2-glass-reinforced epoxy composite...
