To eliminate the unwanted axial strain constraint, in Abaqus the stretch dL/dS at the node of each such element is taken as an internal variable, local to the element (a third internal node is created for this purpose, and so it is not shared with neighboring elements.)
Above paragraph is excerpted from chapter about Euler beam theory in ABAQUS theory manual.
Does anyone know how to get value of dl/dS in UEL user subroutine? This dl/dS axial stretch is also taken as the normal variable similar to nodal displacement and nodal rotation angle.
