Analyses of Composite Insulators with Crimped End- Fittings: Part Ii - Suitable Crimping Conditions
In this research the mechanical behavior of composite suspension insulators with crimped end-fittings manufactured by NGK has been evaluated. Two issues have been addressed in this study. Insulators crimped with the standard, high, reversed and constant high stress conditions have been analyzed for their crimping deformations, and the two and three dimensional compression profiles for the four ...
متن کاملAccuracy Assessment of Ultrasonic C-scan and X-ray Radiography Methods for Impact Damage Detection in Glass Fiber Reinforced Polyester Composites
The present study introduces two quantitative parameters to compare the accuracy of ultrasonic C-scan testing and X-ray radiography methods in the damaged area detection under low-velocity impact in polymer-based composites. For this purpose, the hand lay-up technique of composite processing was employed to prepare the composite specimen. A composite specimen consisting of the glass fiber reinf...
متن کاملStress Field Analysis of V-Notches with Tip Cracks in a Polymer Material Using Digital Image Correlation
In this study, displacement field around v-notches of a poly methyl metha crylate (PMMA) specimen with tip cracks will be analyzed using digital image correlation technique. First intensity factor in combination with in-plane rigid body translations and rotation components will be determined by linear least squares fitting of the displacement field data to the corresponding relations among stre...
متن کاملSkin Irritation to Glass Wool or Continuous Glass Filaments as Observed by a Patch Test among Human Japanese Volunteers
Glass wool and continuous glass filaments have been used in industry. We examined the irritability of those among Japanese. A patch test was performed on 43 volunteers for the followings: glass wool for non-residential use with and without a urea-modified phenolic resin binder, that for residential use with and without the binder, and continuous glass filaments with diameters of 4, 7, 9, and 13...
متن کاملOn 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...
