Abstract
Electronic speckle pattern interferometry has been used to calculate KI and J for compact tension specimens. Automated fringe pattern analysis enables the full field of data to be used with the minimum of operator intervention. Measurements are shown to be accurate to within 10 per cent. The J-measurement procedure employed could form the basis of an automatic fault detection system.Keywords
