Title: | Determination of the plastic zone by laser-speckle correlation | Authors: | Dai, Y.Z. Tay, C.J. Chiang, F.P. |
Issue Date: | Dec-1991 | Citation: | Dai, Y.Z., Tay, C.J., Chiang, F.P. (1991-12). Determination of the plastic zone by laser-speckle correlation. Experimental Mechanics 31 (4) : 348-352. ScholarBank@NUS Repository. https://doi.org/10.1007/BF02325992 | Abstract: | Laser-speckle-pattern correlation is used for the determination of elastic-plastic boundary on the surface of well polished metal specimens. The method employs a converging laser beam to illuminate the test object. Diffracted verging laser beam to illuminate the test object. Diffracted images are recorded and processed on a computer-based vision system. Subsequent image-correlation analysis yields information on the surface deformation of the test objects. The technique is applied to a flat tensile specimen with two circular notches at the central portion. Measured plastic zone is compared with results obtained by the finite-element method. © 1991 Society for Experimental Mechanics, Inc. | Source Title: | Experimental Mechanics | URI: | http://scholarbank.nus.edu.sg/handle/10635/58089 | ISSN: | 00144851 | DOI: | 10.1007/BF02325992 |
