posted on 2018-11-20, 14:52 authored by Rajasekhariah NatarajaNon-linear vibrations of thin-walled shells under
aerodynamic excitation are investigated using Flugge's thin-shell theory, modified to include the effects of large deformations.
The theory is applicable to any type of boundary
conditions and various types of normal loading. The formulation
includes mean or initial deformations of the median surface.
A probabilistic-deterministic analysis of fatigue, representative
of wind effects on earth-borne structures, is proposed based
on the derived stresses and the Palmgren–Miner rule. Extensions
of the non-linear theory to include structural damping and to
analyse single mode. static collapse of thin shells are also
outlined.
In the random vibration analysis; based on energy methods,
the multi-mode random response of thin shells under wind loading
are studied. A fixed-free shell configuration is investigated in
detail, though the formulation is applicable to any type of
boundary conditions. [Continues.]
