Shape function of beam element
WebbThe standard shape functions for quadratic elements are very good. 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. Webb17 juli 2024 · $\begingroup$ The basis functions you chose are not valid. You can't choose the basis functions just like that. They need to possess characteristics such as the …
