M-N-Kappa#
Latest version: 0.2.0 | Documentation build: 10.05.2023
Computing beam-deformations considering non-linear materials#
m_n_kappa is an open source library for using the strain-based method
to compute the stress-distribution of a cross-section considering multi-linear
material models.
The resulting relationship between bending moment M and curvature \(\kappa\) empowers to compute the deformation of a beam under a given load considering non-linear effects like cracking of concrete, plasticizing of steel, etc.
Furthermore, you may compute a composite-cross-section with two sub-cross-sections, where also axial-forces N and strain-differences \(\varepsilon_\mathrm{\Delta}\) are considered. By this approach you may also consider the slip in the composite joint, the multi-linear load-slip-behaviour of shear-connectors and its effect on the deformation of the composite beam.
