نویسندگان
چکیده
Study the tensile damage and fracture behavior of FRP composite materials by the acoustic emission technology, broadband sensors record the acoustic emission signals when composite materials in the process of tensile damage at different fiber angle. The acoustic emission characteristics of FRP composite materials’ tensile damage was analyzed by 3D parameter methods. Analysis the amplitude of composite materials’ acoustic emission signal statistically reveals the development, evolution processes and regulations of FRP composite materials’ tensile damage that are in different angle on macro.

On the Use of Acoustic Emission and Digital Image Correlation for Welded Joints Damage Characterization
A series of tests have been conducted to investigate fatigue damage characterization in corroded welded steel plates using structural health monitoring (SHM) techniques. Acoustic Emission (AE) is a non-destructive testing (NDT) technique with potential applications for locating and monitoring fatigue cracks in service. In the present work, AE is implemented to characterize damage during crack e...
متن کاملAcoustic-Laser Vibrometry for Standoff Detection of Defects in Materials
Standoff methods of non-destructive testing (NDT) offer flexibility over traditional methods of inspection which typically require physical contact with the material being measured. The benefits are that difficult to access locations can be inspected and measurements of a large area can be made more quickly. Acoustic-laser vibrometry is a robust standoff NDT technique for composite materials, s...

Abstract Fiber-reinforced polymer (FRP) strengthening and retro fi tting of concrete elements, such as beams, columns, slabs, and bridge decks, have become increasingly popular. Nonetheless, rapid and reliable nondestructive testing techniques (NDT) that are capable of remotely assessing in-situ integrity of retro fi tted systems are needed. Development of a robust NDT method that provides an a...

In this study, the longitudinal and hoop tensile strengths of an industrial ±55° Glass Reinforced Epoxy (GRE) pipe with eighteen layers as well as the associated failure mechanisms are determined. To obtain the longitudinal and hoop tensile strengths values, three specimens are cut from the studied GRE pipe in each direction. A comparison is done between both the strength values, and the fractu...
متن کاملBiomimetic self-healing of advanced composite structures using hollow glass fibres
The use of functional repair components stored inside hollow reinforcing fibres is being considered as a self-repair system for future composite structures. The incorporation of a self-healing capability within a variety of materials, including fibre reinforced polymers (FRPs), has been investigated by a number of workers previously. This paper considers the placement of self-healing plies with...
