Abstract: Longitudinal cracks were observed in asbestos‐cement pipes that were in service for some time before bursting. Preliminary tests using a slitting technique showed residual stresses in the hoop directions. Absolute peak ...

Abstract: Normalized minimum light intensity of a three‐dimensional photoelastic medium, measured in a direct illumination polariscope by crossed arrangement of filters, is explored as a reliable characteristic quantity. The variation ...

Abstract: The exact solution of shallow spherical shells subjected to apex loads contains arbitrary constants that appear in the stress and normal displacement functions. In general, these constants are obtained from the conditions ...

Abstract: Nondestructive photoelastic stress analysis of elliptical holes in thick plates was carried out. Using Plexiglas as a model material, the scattered photoelastic technique was used. In a novel approach, the residing ...
