Incompatible mode is a feature designed to improve the bending behavior of low order elements. Briefly, by using this feature elements shows a more realistic response under bending moments. As I have focused several times in my video coarse, deep understanding of different features of a software is the most part of any numerical modeling. […]
Shear locking error As it is said earlier, reduced integration elements are suffering hourglass effect due to their low bending stiffness. On the other hand higher bending stiffness of full integration elements might cause another numerical issue, called shear locking effect. Fully integrated first order elements, such as solid elements, Timoshenko beam elements, may exhibit […]
