classEAGJ_BeamProperty
Information
Beam combined properties for use with the DeployStructLib.Parts.Beam block. To use these properties, add DeployStructLib.Properties.EAGJ_BeamProperty to your model, provide the properties, and give the Beam block the name of this record. Also be sure to set "useEAGJ" to true in the Beam block.
All properties, except for centroid location, must be provided.
Damping is modeled using Rayleigh damping, where the damping matrix C is a linear combination of the stiffness matrix K and the mass matrix M as follows:
C = αM + βK
Values of "alpha" and "beta" should generally be kept small (~0.01 - ~0.1), or the simulation may struggle to converge. If convergence is an issue when damping is used, try setting both "alpha" and "beta" to zero. If that converges, then gradually increase the damping.
