Strain Analysis of a Disk Subjected to Diametral Compression by Means of Holographic Interferometry
1973
Applied Optics
Preserved Fulltext
Two simultaneous holograms and several directions of observation are utilized to determine the components of displacement and strain in the disk. A reference strip is introduced to relate the fringe orders in the two holograms. A very good agreement is obtained between the holographic results and the elasticity theory solution. The obtained displacement field is estimated to be accurate to 8 x 10-6 cm, which is approximately one-eighth the wavelength of the laser light utilized to obtain the holograms.
