The joint between the bogie and the stabiliser was unfavourably stressed at 29 kN/cm

.
The ratio between membrane and bending stress was 22/78, which is also unfavourable.
Global behaviour of the construction, local behaviour, and stress concentration can be
precisely obtained using plate model, Fig. 24. Obtained stress field is presented in Fig. 25.

3.9. Modelling of the failure and recovery of storage tank (
D
= 20 m,
H
= 20 m)
Failure of a storage tank occurred while proof pressure testing with air in plant “HIP,”
in Pančevo. The structure consists of an internal storage tank anchored to the ground; the
external tank is simply supported; with insulation (fiberglass) between the two tanks and
pearlite between the roofs; anti-fire safety pipes. The tank model is given in Fig. 26, and
elements for analysis in Fig. 27. Based on this, the tank has been syccessfully recovered.
