The Beam Element in Large Displacements Example: Assume the following 2-node beam element. Evaluate the coordinate and displacement interpolations and derivatives required for the setup of the strain displacement matrices in the TL and UL formulation.

The Beam Element in Large Displacements Example: First we need to calculate the nodal coordinates at times t and 0 ( t x 1 , t x 2 ), ( 0 x 1 , 0 x 2 ). Using the corresponding geometries and the following formula: t x i = N∑ N t k x k i + t 2 k=1 N∑ k=1 a k N k t V k ti + s 2 N∑ k=1 where N k are linear shape functions, we obtain: b k N k t V k si, i = 1, 2, 3 Institute of Structural Engineering Method of Finite Elements II 43
