m_n_kappa.MomentAxialForceCurvature

class m_n_kappa.MomentAxialForceCurvature(sub_cross_sections, axial_force, strain_position, positive_curvature=True)

Bases: AxialForcePoint

compute a moment-axial-force-curvature point with moment-axial-force and strain-position-point

New in version 0.2.0.

Parameters:

• sub_cross_sections (list[Crosssection] |) –

• axial_force (float) –

• strain_position (StrainPosition) –

• positive_curvature (bool) –

:param tuple[Crosssection: sub-cross-sections the overall cross-section consists of :param Crosssection]: sub-cross-sections the overall cross-section consists of :param axial_force: Axial-force that is applied in sign and magnitude to the first given cross-section.

On the second cross-section it is applied with switches sign.

Parameters:

• strain_position (StrainPosition) – strain- and its position, that is to be considered by determining the curvature in the first cross-section

• positive_curvature (bool) – True indicates positive curvature and leads to considering a positive curvature

• sub_cross_sections (list[m_n_kappa.crosssection.Crosssection] | tuple[m_n_kappa.crosssection.Crosssection, m_n_kappa.crosssection.Crosssection]) –

• axial_force (float) –

Raises:

• ValueError – If not exactly two cross-sections are given in cross_sections:

• ValueError – If neither strain nor axial_force are given:
