Ls dyna shell element formulation
WebShells. All shell elements include membrane, bending and shear deformation. The default Belytschko-Tsay formulation is the most economical and should be used unless features particular to other formulations are required e.g.: Hughes Liu: can o set the mid-plane of … Under some circumstances the displacements calculated by the finite … WebSHELL163 is a 4-node element with both bending and membrane capabilities. Both in-plane and normal loads are permitted. The element has 12 degrees of freedom at each node: …
