This chapter describes the theory underlying each ANSYS element. The explanations are augmented by references to other sections in this manual as well as external sources.

The table below the introductory figure of each element is complete, except that the Newton-Raphson load vector is omitted. This load vector always uses the same shape functions and integration points as the applicable stiffness, conductivity and/or coefficient matrix. Exceptions associated mostly with some nonlinear line elements are noted with the element description.
