Abstract: LAMPAT and ANSYS are analysis tools that can be used together to evaluate the mechanical integrity of structures of laminar construction. The two codes originate from two different areas of analysis. Their default coordinate systems have different orientations. To properly examine a structure, the directional properties used by LAMPAT must be transformed into the proper input coordinate directional properties for ANSYS. This has been done for some time already, but as the structures being analyzed become more complex, this coordinate system transformation has become a tool requiring some additional thought. This report describes using of cylindrical and Cartesian coordinate system orientations and local element coordinate system results within ANSYS to facilitate the analysis of laminate structures with ply layers parallel to curvilinear profiles.
