19 July 1996 Novel material studies by automatic grating interferometry
Author Affiliations +
High sensitivity, automatic grating interferometry system is shown as the effective experimental tool for the material structure studies and determination of local material constants. The investigations of local Poisson ratio distribution in multilayer glass fiber/epoxy composite, strain distribution around the wire actuator in smart material (carbon fiber/epoxy + optical fiber + wire actuator) and mechanical relation in the area of a few grains in two-phases austenitic-ferritic steel are described and discussed.
