Damping assignment for a structural analysis model
StructuralDampingAssignment object contains the damping
model and its parameters for a structural analysis model. A
container has a vector of
objects in its
To set damping parameters for your structural model, use the
RegionType — Region type
Region type, returned as
'Face' for a 2-D region, or
'Cell' for a 3-D region.
RegionID — Region ID
Region ID, returned as a positive integer. The toolbox defines damping parameters for the entire geometry.
DampingModel — Damping model type
Damping model type, returned as
Alpha — Mass proportional damping parameter
Mass proportional damping parameter, returned as a nonnegative number.
Beta — Stiffness proportional damping parameter
Stiffness proportional damping parameter, returned as a nonnegative number.
Zeta — Modal damping ratio
nonnegative number | function handle
Modal damping ratio, returned as a nonnegative number or a function handle. Use a function handle when each mode has its own damping ratio. The function must accept a vector of natural frequencies as an input argument and return a vector of corresponding damping ratios. It must cover the full frequency range for all modes used for modal solution.
