Optical methods for measurement of fatigue crack closure: moire interferometry and digital image correlation
This paper describes three different optical techniques for the measurement of in-plane displacements close to the crack tip which can then be used to determine the presence of crack closure in propagating fatigue cracks. Conventional temporal phase shifting moiré interferometry is described first,...
