Shape function of beam element
Webb7 apr. 2024 · Shape function for B21 (Timoshenko beam) element in Abaqus. I am wondering what are the appropriate shape/interpolation functions for the B21 element since it has 3 DoF per node, but is stated as linear interpolation element. I know there is a distinction between nodal DoF and interpolation order and I am looking for the relation … WebbWe saw that the shape function is used to interpolate the deflection at each point in between the element. The finite element solution of a beam element is a cubic …

Most finite element programs use these standard functions. For linear elements this is not the case: linear elements exhibit all kind of weird behavior such as shear locking and volumetric locking.
Webbof beam elements for the member of interest, the desired mode shape can be obtained. However, this presents another problem. Beams are, by default, “welded” at the joint. If that is not the intent of the model, this must be addressed. Two ways are presented in the section for beam elements.
