Web• A shell model is a part that you model using shell elements like triangles and quadrilaterals. Typically, you use shell modeling when your part is relatively thin compared to its length and width. To meet the criteria for shell models, your part must have either a constant or a variable thickness in native or FEM modes. WebAbaqus/Standard has two types of thin shell elements: those that solve thin shell theory (the Kirchhoff constraint is satisfied analytically) and those that converge to thin shell theory as the thickness decreases (the Kirchhoff …
