Fig. 2From: Introducing the Logarithmic finite element method: a geometrically exact planar Bernoulli beam elementParameterization of a two-dimensional beam element. The coordinate axes are related to the canonical coordinate system in the Euclidean plane by the relations \(x = \mathrm{Re}\) (x \(_0\)) and \(z = -\mathrm{Im}\) (x \(_0\))Back to article page
