Structures describes the derivation of structural element matrices and load vectors as well as stress evaluations. General Element Formulations gives the general element formulations used by this element.
SOLSH190 is a 3-D solid element free of locking in bending-dominant situations. Unlike shell elements, SOLSH190 is compatible with general 3-D constitutive relations and can be connected directly with other continuum elements.
SOLSH190 employs enhanced strain formulations (Simo and Rifai(), Simo et al.()) to improve the accuracy in in-plane bending situations. The satisfaction of the in-plane patch test is ensured. Incompatible shape functions are used to overcome the thickness locking.
