Study On The Deformation Band Characteristics In Mild Steel Using Digital Image Correlation
نویسندگان
چکیده
This study investigates the strain localizations associated with Lüders deformation in mild steel using digital image correlation (DIC), a non contact, nondestructive, full field measurement technique for strain mapping. The focus is on the two substantial areas of interest such as shear deformation accompanying strain localization during Lüders instability and the complex morphology of Lüders deformation bands. The results provide insights into nature of shear deformation associated with the Lüders band front propagation (band growth) and some important morphological features of complex Lüders band. Keywords— mild steel; digital image correlation; shear strain; complex Lüders band; yield point phenomena

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...

Quality inspection is an indispensable part of modern industrial manufacturing. Steel as a major industry requires constant surveillance and supervision through its various stages of production. Continuous casting is a critical step in the steel manufacturing process in which molten steel is solidified into a semi-finished product called slab. Once the slab is released from the casting unit, th...
متن کاملMeasurement of Creep Deformation across Welds in 316H Stainless Steel Using Digital Image Correlation
Spatially resolved measurement of creep deformation across weldments at high temperature cannot be achieved using standard extensometry approaches. In this investigation, a Digital Image Correlation (DIC) based system has been developed for long-term high-temperature creep strain measurement in order to characterise the material deformation behaviour of separate regions of a multi-pass weld.
