struct.node.resultant
Syntax
- m = struct.node.resultant(p<,ires>)
Get stress resultants last calculated for the elements connected to this node.
Will return a 1x6 matrix of the stress resultants in this order: { Mx, My, Mxy, Nx, Ny, Nxy, } URGENT: DR: previous braced expression was flagged like this: :flag2:-{ M_x,M_y,M_xy,N_x,N_y,N_xy }- : why?]. Note that the Qx and Qy1 terms are not valid at nodes because they are constant over an element.
Stress resultants are expressed in the node surface system; see the
structure shell recover surface
,structure geogrid recover surface
, andstructure liner recover surface
commands.If the optional argument ires is provided, then the function will return that specific stress resultant (indexed as the order above) as a single value.
Note that stress resultants must be calculated with the
structure shell recover
,structure geogrid recover
, andstructure liner recover
command. See also thestruct.shell.resultant.valid
function.Returns: m - a 1x6 matrix of all stress resultants, or a single value of a specific resultant
Arguments: p - a pointer to a structural element node
ires - an optional argument indicating a specific resultant index, from 1 to 6
