material
name
radius_of_gyration Radius of gyration \kappa is given by dividing the height of the plate by \sqrt{12}.
velocity Velocity of the component v_{component}.
velocity_level Velocity level L_v.
volume Volume V of the component.
width float(x) -> floating point number
area[source]

Area of the plate.

A = l w

with:

  • length l
  • width w
area_moment_of_inertia[source]

Area moment of inertia.

J = \frac{h^3}{12}

with:

  • plate thickness/height h

Following equation includes resistance to deflection and is thus part of the bending wave subsystem:

J = \frac{h^3}{12 \left( 1 - \nu^2 \right)}

mass_per_area[source]

Mass per unit area. Also called the surface density.

m^{''} = \rho h

with:

  • density \rho
  • plate thickness/height h
radius_of_gyration[source]

Radius of gyration \kappa is given by dividing the height of the plate by \sqrt{12}.

\kappa = \frac{h}{\sqrt{12}}

with:

  • plate thickness/height h

See Lyon, above eq. 8.2.5
