| Title |
Design of cantilever elements of safety valves subject to plastic deformation |
| Author(s) |

| Abstract |
We consider problems of analytical and numerical design of
cantilever elements supporting the piston of a one-time safety valve.
Computations of plastic bending are based on the power law
approximation of the deformation curve. Shape variation for large
displacements is taken into account.
The analytical approach is based on the model of a rigid cantilever
with hardening plastic joint at the plane of clamping. For numerical
calculations, the cantilever axis is partitioned into finite
segments, the loads are prescribed by small displacement increments, and
the Hooke-Geeves direct optimization method is used for finding the
corresponding force as an argument of the error function which is
the difference between the given and the calculated displacements.
The force characteristic of the loading process has a maximum.
The calculated and the experimental
values of the maximal tension of the force characteristic are in good
agreement. |
