Structural Health Monitoring using Artificial Immune System

Artificial-immune-system approach enables monitoring structural health

Wireless sensor networks are emerging as useful tools for structural-health monitoring (SHM). While such networks offer a number of advantages, SHM systems face many challenges. Major issues include provision of sustainable, long-term, and autonomous monitoring, active detection and identification of structural damage, and development of adaptive approaches that can adjust to changing monitorin...

Structural Health Monitoring of Composite Structures using Artificial Intelligence Protocols

This study discusses a structural health monitoring (SHM) system developed to detect the presence of delamination, and predict its location and size in a composite structure. Two structures are considered in this study: a composite beam and a T-joint structure used in ships. Finite element (FE) models of these structures are created, embedded with delaminations, and the strain distribution alon...

Damage detection and structural health monitoring of ST-37 plate using smart materials and signal processing by artificial neural networks

Structural health monitoring (SHM) systems operate online and test different materials using ultrasonic guided waves and piezoelectric smart materials. These systems are permanently installed on the structures and display information on the monitor screen. The user informs the engineers of the existing damage after observing signal loss which appears after damage is caused. In this paper health...

Structural Health Monitoring Using Neural Network Based Vibrational System Identification

Composite fabrication technologies now provide the means for producing high-strength, low-weight panels, plates, spars and other structural components which use embedded fiber optic sensors and piezoelectric transducers. These materials, often referred to as smart structures, make it possible to sense internal characteristics, such as delaminations or structural degradation. In this effort we u...
