Abstract

THIS WORK PRESENTS A HYBRID EXPERIMENTAL TECHNIQUE FOR RESIDUAL STRESS ANALYSIS IN PIPES DUE TO SOIL-PIPE INTERACTION. IT WAS USED A VARIATION OF DIGITAL SPECKLE PATTERN INTERFEROMETRY (DSPI) COMBINED WITH A SMALL INDENTATION SETUP FOR ACQUIRING RADIAL DISPLACEMENT POINTS. DATA COLLECTED ARE FITTED UNDER THE AIRY STRESS FUNCTIONS METHOD FOR THE DETERMINATION OF DISPLACEMENTS AND STRAIN COMPO-NENTS. THE RADIAL DISPLACEMENT DATA IS FITTED IN ORDER TO EXTRACT AIRY STRESS FUNCTION COEFFICIENTS IN A SHORT COMBINATION SELECTED SPECIFI-CALLY FOR PIPE STRESS ANALYSIS. THIS TECHNIQUE IS OF GREAT UTILITY AS AN AUXILIARY APPROACH TO THE ACTUAL FIELD DATA COMPILATION. KEYWORDS: HYBRID TECHNIQUE, AIRY STRESS FUNCTION, INSTRUMENTED INDENTATION, PIPELINE STRESSES.
