plates or when Poisson cannot be computed from
G.
DENSITY specifies weight density.
ALPHA Co-efficient of thermal expansion.
DAMPING or CDAMP
Damping ratio to be used in computing the modal
damping by the composite damping method.
f
1
f
2
Value of the corresponding constants. For E, G,
POISSON, DENSITY, ALPHA and damping.
For plates only, the first value is for local x
direction and the second for local y.
