Strain Analysis on a T-branch Pipe Connection with 3D-ESPI and FEA

Image of triform T-branch

Speckle interferometric techniques (ESPI) offer theoretically good opportunities to validate Finite Element Analysis (FEA). The practical approach is typically limited to the comparison of displacement values. In this paper the analysis of a triform T-branch will be shown and the comparison of the simulated strain values will be compared with data, obtained from quantitative 3D-ESPI-measurement.
