      The stresses at the section integration points of the integrated beam elements, such as the elform 1 beams, are written in the elout file. This is output by the keyword *DATABASE_ELOUT and will include the beam elements specified on *DATABASE_HISTORY_BEAM. The stresses and axial strain of integrated beams are also written in d3plot when BEAMIP>0 on *DATABASE_EXTENT_BINARY. These can be fringed be loading d3plot in LS-PrePost and selecting: FEA> Post> Fringe Component> Beam. From the from the drop-down menu at the bottom left of the Fringe Component window the user can select to fringe the maximum, minimum, average (“Ave”) stress and strain among the beam integration points, or the stress and strain at each integration point by selecting “BPt”. Furthermore, the time history of the beam stresses and axial strain can be plotted by selecting: FEM> Post> Hist> “E-Type: Beam”> (check the “Element” or “Int Pt”).
