Hygroscopic Swelling
Hygroscopic swelling is an internal strain caused by changes in moisture content. This strain can be written as
where
β
h
is the coefficient of hygroscopic swelling,
c
mo
is the moisture concentration, and
c
mo,ref
is the strain-free reference concentration. The temperature is assumed to be constant over the cross section of the truss element.
The settings for the Truss interface are the same as described for the Beam interface (excluding the hygroscopic bending options). See
Hygroscopic Swelling
in the documentation for the Beam interface.
