Title: Automatic measurement of residual stresses in tempered tumbler. 9 p.
Language: English
Keywords: automatic measurement * residual stress * glass * photoelasticity
ABSTRACT. Automatic measurement technique has been developed to determine
residual stresses in strongly tempered tumblers. It is shown that when
the stress distribution is close to parabolic one, it is possible to
determine axial residual stresses in the wall of the tumbler using only
one image taken by video camera. The experimental setup and data
acquisition software design are described and some examples are given.
