The aim of this paper is to analyze the stress field of
a complex geometry model of pipe branches loaded
with internal pressure of 10 bar. The analysis will be
done by comparing method of strain gauges and a
new one (state-of-the-art) 3D optical method to finite
element method, as a numerical method. Finite
element method is used to determine critical points
(places of expected stress concentration) in the
branch. In these places (or at least close to them)
strain gauges are placed. The main limitation of the
method of strain gauges is that it is not possible to
place them anywhere. Whole stress field can be
obtained using a system for 3D optical stress measurement based on the method of digital image
correlation (Aramis system). Comparing the results of
strain gauges and Aramis-system the advantages
and disadvantages of modern and classical experimental methods are shown.
