A typical two dimensional cross section of a prismatic solid may have arbitrary geometric shape, material properties and boundary conditions. In this finite element technique, an infinitely long element of triangular cross section is used as the basic method of analysis. The three components of displacement within each element are expanded in terms of trigonometric functions which permits the three dimensional analysis to be reduced to a series of two dimensional analyses.
