A more quantitative inspection of the simulation results can be done by considering the thickness profiles along intrados and
extrados lines of the parison shown in Fig.
(1) The numerical model and the mesh were generated based on the cross section, plan, and front view drawings and on the geometric definition of the arches in the intrados and
extrados. As a result, a detailed 3D geometry was obtained that was then used to perform a thermomechanical calculation.
Here it is important to notice that in the
extrados location the tensile strength decreases rapidly, below the minimum criteria.
Figure 3 shows the temperature drop ([DELTA]T) along the
extrados of pipe wall at different inlet temperatures.
4, compared with the group N, both the pain threshold pressure of abdominal elevation and
extrados were significantly decreased in the NMS rats.
The warming of the vault
extrados by 6[degrees]C causes tensile forces in the ribs comparable to loading by self weight.
The dorsal surface of the wing (
extrados) is the most critical for lift production.
Like its model the Pantheon, its diameter (56 braccia externally) corresponds to its height (to the vault
extrados).
It is observed that there is always a depression zone at the
extrados. The pressure distribution is not identical in all passages of the volute.
Removal is carried out with the following three steps: (1) unscrewing the eight bolts from the cylindrical caps, (2) uplifting by 4-5 mm the upper R/C beam of the ground floor by means of vertical hydraulic actuators introduced between the
extrados of the column capital and the intrados of the beam, and (3) shifting the device out of the capital.
