摘要：
This investigation applied the digital image correlation technique - DIC - to a thin walled cylindrical vessel that contained longitudinal and circumferential metal loss defects. The uncertainty of the DIC technique was assessed by measuring strain fields induced by opening soft drink beverage cans and by comparing DIC results with electrical resistance strain gage measurements. Using the equations proposed by (DNV RP F-101) and by (Kastner 1981), the investigation also addressed the calculation of the burst pressure of a cylindrical vessel with simulated corrosion defects.
