Fig.7-7 Test situation of the multi-perforated plate(Left figure)
The test models that simulate a part of the tube sheet structure of a heat exchanger were subjected to cyclic displacement loading at 550 ℃ to generate cracks, and the number of cycles until crack generation was experimentally determined. Two types of test models with different plate widths and hole distances were used.
Fig.7-8 Strain simulation by inelastic analysis(Right figure)
Stress and strain were simulated by finite element analysis with 1/4 sector models. Larger strain was observed on the inner surface of the outermost hole (Red arrow).
