struct.shell.prop.anis
Syntax
- l := struct.shell.prop.anis(p,itype)
- struct.shell.prop.anis(p,itype) := l
Get/set the anisotropic material properties as a list of 6 values.
Membrane stiffness is indicated by itype = 1, and bending stiffness is indicated by itype = 2.
If the element does not have anisotropic properties an error will occur.
See the
structure shell property
,structure geogrid property
, andstructure liner property
commands.Modifying the stiffness of an element can result in instability if done during cycling. Dependent values should be forced to update using
struct.force.update
. See the documentation ofstruct.force.update
for comments on the cost.Returns: l - the shell anisoptric material stiffness coefficients for itype
Accepts: l - the shell anisoptric material stiffness coefficients for itype
Arguments: p - a pointer to a shell element
