Pattern Recognition of Barely Visible Impact Damage in Carbon Composites Using Pulsed Thermography

چکیده
This article proposes a novel framework to characterize the morphological pattern of barely visible impact damage using machine learning. Initially, sequence image processing methods is introduced extract contour, which then described by Fourier descriptor-based filter. The uncertainty associated with contour under same energy level investigated. A variety geometric features are extracted develop an artificial intelligence model, effectively groups tested 100 samples impacted 5 different levels accuracy 96%. Predictive polynomial models finally established link three selected features. It found that major axis length has best prediction performance, R 2 value up 0.97. Additionally, caused low exhibits higher than high energy, indicating lower predictability.

15 صفحه اولProgressive Damage Analysis of Laminated Composites using Continuum Damage Mechanics
In this paper, progressive damage and global failure of composite laminates under quasi-static, monotonic loading are investigated using 3D continuum damage mechanics. For this purpose, a finite element program has been developed using an eight-node 2D layered element including layer-wise plate theory. Damage analysis of a single orthotropic layer under various uniform in-plane and transverse l...
متن کاملMonitoring Moisture Damage Propagation in GFRP Composites Using Carbon Nanoparticles
Glass fiber reinforced polymer (GFRP) composites are widely used in infrastructure applications including water structures due to their relatively high durability, high strength to weight ratio, and non-corrosiveness. Here we demonstrate the potential use of carbon nanoparticles dispersed during GFRP composite fabrication to reduce water absorption of GFRP and to enable monitoring of moisture d...
متن کاملMonitoring Damage Propagation in Glass Fiber Composites Using Carbon Nanofibers
In this work, we report the potential use of novel carbon nanofibers (CNFs), dispersed during fabrication of glass fiber composites to monitor damage propagation under static loading. The use of CNFs enables a transformation of the typically non-conductive glass fiber composites into new fiber composites with appreciable electrical conductivity. The percolation limit of CNFs/epoxy nanocomposite...
