TL;DR: In this paper, a digital speckle pattern interferometry and hole drilling combined system is developed to determine the magnitude of the residual stress in a aluminum thin plate subjected to an uniform uniaxial tensile load.

TL;DR: In this paper, a combined system of blind hole drilling and digital speckle pattern interferometry is used to determine the magnitude of the residual stress induced in an aluminum plate subjected to uniaxial tension.

TL;DR: In this article, an optical method was used for the determination of the plastic zone size generated on the surface of a notched metal specimen under conditions of low-cycle fatigue, using white-light scattering generated by plastically induced surface roughness.

TL;DR: In this article, a digital image measurement (DIM) system was used to study the plastic damage accumulation around a notch under conditions of low-cycle fatigue, and the results obtained using this measurement system were compared with those attained by means of a recrytallization technique.

TL;DR: In this article, the fatigue damage accumulation process around a notch is studied using a noncontact digital image measurement system, which incorporates a contrast correlation method to evaluate the level of plastic damage at each point of the studied area of the specimen from two images acquired before and after the introduction of fatigue deformation.
