Impact Force Reconstruction for Structural Health Monitoring of Composite Beam

Structural Health Monitoring for Composite Materials

A composite material can be defined as a combination of two or more distinct materials at a macroscopic level to attain new properties that can’t be achieved by those of individual components acting alone. Different from metallic alloys, each material keeps its own chemical, physical and mechanical properties [1]. Composite materials have reinforcing and matrix phases. The reinforcing phase wit...

A phase reconstruction algorithm for Lamb wave based structural health monitoring of anisotropic multilayered composite plates

Platelike structures, made of composites, are being increasingly used for fabricating aircraft wings and other aircraft substructures. Continuous monitoring of the health of these structures would aid the reliable operation of aircrafts. This paper considers the use of a Lamb wave based structural health monitoring SHM system to identify and locate defects in large multilayered composite plates...

Structural Health Monitoring in Composite Automotive Elements

Structural Health Monitoring of Composite Laminates Through Ultrasonic Guided Wave Beam Forming

The availability of military platforms is affected by design methods, damage detection, maintenance, and logistics. Structural health monitoring provides a means of detecting damage, which can be used to predict future structural performance of the platform and effectively schedule maintenance. Ultrasonic guided waves can be employed as an active structural health monitoring technique in a vari...

Structural Health Monitoring of Composite Materials Using Piezoelectric Sensors

Structural Health Monitoring (SHM) denotes a system with the ability to detect and interpret adverse " changes " in a structure in order to improve reliability and reduce life-cycle costs. The greatest challenge in designing a SHM system is knowing what " changes " to look for and how to identify them. This paper focuses on the relationship between sensing systems and their ability to detect ch...
