Shell features:

  • thickness h=0.05m,

  • radius of curvature R=1.m

  • width= AB= CD=0.1m,

  • angle \(\alpha\) is chosen as

Note: the geometry is very flat in \((\mathit{xy})\)

1.2. Material properties#

The properties of the material constituting the plate are:

\(E=2.E+11\mathit{Pa}\)

Young’s module

\(\nu =\mathrm{0,3}\)

Poisson’s ratio

\(\rho =7800.\mathit{kg}\mathrm{.}{m}^{-3}\)

Density

1.3. Boundary conditions and loads#

No boundary conditions: free-free dynamic analysis

1.4. Initial conditions#
