Photostress: A Proven Optical Method for Stress Analysis
MM Matrix Integrity (M) Sdn Bhd (Malaysia) invited PETRONAS Group Technical Solutions to observe a demonstration of the PhotoStress® method. The demonstration’s purpose was to confirm that the PhotoStress® technology is reliable for measuring surface strain at defect and away from the defect areas (nominal). Qualitative and quantitative analyses were performed on a carbon steel pipe spool, and results were validated against strain gage readings and empirical values.
