ANSYS Rayleigh Damping, ALPHA & BETA

ANSYS Rayleigh Damping, ALPHA & BETA

ANSYS Rayleigh Damping, ALPHA & BETA

(OP)
I am trying to run a basic model in ANSYS of a cantilever beam.  What does ANSYS default the values of ALPHA and BETA to if they are not input into the program?

RE: ANSYS Rayleigh Damping, ALPHA & BETA

As with all defaults in Ansys chances are if it isn't specified...then it defaults to zero.  Damping is not different.

RE: ANSYS Rayleigh Damping, ALPHA & BETA

Hi,
correct, they default to zero. Anyway, in static structural damping is unrelevant.

Regards

RE: ANSYS Rayleigh Damping, ALPHA & BETA

(OP)
It is not a basic static structural analysis.  I am trying to apply a concentrated end load to the beam that has a sinusoidal trend.  The P(t) load curve is modeled with the function 4*sin(omega*t).  I am new to ANSYS so I am not sure exactly how to apply this type of load.  Do I use a harmonic analysis?  And if so, how is that type of load applied?
