Abstract:
A phenomenological model for the experimental determination of the principal stress magnitudes and directions using the holographic interferometry and probing hole method is proposed. This non-invasive in situ method allows for the analysis of stress-strain states for a wide range of objects. The model establishes a straightforward relationship between the interference order and planar stress magnitude. The presented results have a practical importance for assessing the performance capability and safety of technical objects, as well as of their components and parts, during commissioning or operation.
Keywords:
holographic interferometry, probing hole method, planar stress state, non-destructive testing, measurement of principal stresses.
