Practical Applications of 2D Shell Elements: Unveiling Their Versatility in Structural Analysis

Shell elements are finite elements used in structural analysis to model thin-walled structures or components, such as plates, shells, and membranes. These elements are designed to capture the behavior of these structures, which have two dominant dimensions (length and width) and a relatively small thickness compared to the other dimensions.

Shell elements are used to represent the behavior of structures subjected to bending, membrane forces, and in-plane and out-of-plane loads. They are particularly useful in analyzing structures with large aspect ratios, where the thickness is significantly smaller compared to the other dimensions.

These elements have six degrees of freedom per node, including three translations (u, v, w) and three rotations (θx, θy, θz). They can accurately capture both bending and membrane behavior of thin-walled structures. Examples of 6-DOF shell elements include the MITC4 (Mixed Interpolation of Tensorial Components) and DKQ (Discrete Kirchhoff Quadrilateral) elements.
