Elastic "Bulk" modulus of porous material and corresponding loss factor are
determined using specific device, in which a material sample is excited by an
electrodynamic shaker controlled in displacement (laser transducer) and resulting
force (load cell): from the Transfer Function measurement the F/S and "eta"
values are measured. Poisson Ratio can also be measured using another Laser
Velocimeter pointed on sample side.
The device ensemble for the SCS 902A system is also available as a separated
set which can be connected to other acquisition and analysis system.
