struct.link.model.stiffness

Syntax

m := struct.link.model.stiffness(p<,idof>)

struct.link.model.stiffness(p<,idof>) := m

Get/set the stiffness used by each 1-D force-displacement model. The function returns a 6×1 (3×1 in 2D) matrix with the values in all six degrees-of-freedom, or if the optional idof argument is provided, the value in one specific degree-of-freedom.

Returns:

m - a 6×1 (3×1 in 2D) matrix representing the stiffness used by each force-displacement model, or a single value in a specific degree-of-freedom

Arguments:

p - a structural link pointer

idof - an optional degree-of-freedom, from 1 to 6 (1 to 3 in 2D)
