These shell elements are geometrically 2D but spatially 3D, which means they are suitable for 3D thin to moderately thick structures. ![]() Shell elements are suitable for think structures having thickness at least 20 times than the span. Shell elements on the contrary are ideal for such applications, which apart from simulating the bending effects more accurately also consume less computational power compared to solid elements. Shear Stress Locking Phenomenon Observed in Solid Shells for Thin Plate Such problem can be resolved by refining the mesh with more number of elements, but it will consume more computational time. This causes the stress and strain distribution to distribute unevenly, causing drastic variations in the results. While these DOFs are suitable to evaluate bulk solid structures, for thin walls these elements have locking tendency while transferring the results of bending effects to adjacent element. Solid elements particularly have three transitional degrees of freedom at each node. While in most 3D simulations, solid elements are required, it is found that these elements do not give desired results for thin and slender structures. The results of finite element analysis hugely depend on the type of element used to convert the geometry into smaller elements. Using Shell Elements for Your FEA Simulation
