Tests Made with Optical Stethoscope developed by Professor J. E. Shrader, Drexel Institute of Technology
Abstract
The fusion between halves of a laminated plate is so strong that no difference in the vibration record of a known laminated plate and that of a comparable solid plate could be detected by use of the instrument under test. The conclusion was the same both for free and for forced vibration of the plates.
