Mapping Full-field Bond Stress Distribution on Concrete using Digital Image Correlation Results

Reza Aghlara, Redzuan Abdullah and Mahmood Md. Tahir

Abstract:
A pull-out concrete specimen was subjected to tensile load in order to obtain the bond stress distribution on its surface using the results of Two Dimensional Digital Image Correlation (2D DIC). Digital images were taken from front face of specimen by a typical digital camera (Nikon D80) and used as input data of correlation software for strain analysis. The correctness of analysis results were controlled by results of linear variable differential transformer instrument LVDT which it was installed by specimen in the experiment. After obtaining bond strain components on the face of specimen, the related bond stress components were calculated numerically with considering the specimen face as plain stress. The results show high capability of used method and technique for investigation on bond in concrete.
