7th DoF (warping) - 1D internal forces

1D internal forces - new results

In case warping is activated in the projects, there are extra 1D internal forces present:

- Primary torsional moment - M_xp [kN m]

- Secondary torsional moment - M_xs [kN m]

- Warping bimoment - M_w [kN m^2]

Primary and secondary torsional moments

The torsional moment M_x is split into primary and secondary part in case warping is activated in the project. It has a standard unit as any moment of force.

M_xp + M_xs = M_x (torsional moment)

Warping bimoment M_w

There is a new 1D internal force result in case warping is activated in the project: warping bimoment, M_w. It has an unit force * length^2, as it represents two bending moments on an arm.

Altering the bimoment unit is explained in the chapter "7th DoF (warping) - nodal reaction".
