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
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.
