Can My MITC Shell Element Beat ANSYS? | FEM coding + Math explanation

The MITC (Mixed Interpolation of Tensorial Components) shell element is a finite element formulation specifically designed to alleviate numerical locking phenomena—most notably shear locking and membrane locking—which can occur in thin shell analyses using standard displacement-based elements. This is the repo: https://github.com/luchete80/MITC_python The core idea behind the MITC approach is to apply reduced or mixed interpolation selectively to the transverse shear strain and membrane strain components. This enables the element to represent the physical behavior of thin shells more accurately without requiring excessive mesh refinement. Key characteristics: Locking-free behavior for both bending-dominated and membrane-dominated problems. Suitable for thin and moderately thick shell structures. Compatible with both linear and nonlinear geometric formulations. Applicable to isoparametric quadrilateral and triangular elements (e.g., MITC4, MITC9). Often used in Total Lagrangian or Updated Lagrangian frameworks. The MITC formulation strikes a balance between computational efficiency and accuracy, making it widely used in structural mechanics, aerospace, and mechanical engineering applications where thin-walled components are modeled.
