By use of a Microsoft Excel Macro, Auto FLD generates FLD (Forming Limit Diagrams). There are many options available to customize the charts. FLD charts may be calculated on either Metric or English units of measure for thickness. Since the location of the FLDo point is a function of both thickness and n value the user may select a range of thicknesses and n values for printing charts of various values of thickness and n values. Normal FLD charts may be printed or a series of iso-thickness strain lines can be added to the FLD charts. Analyzed strain grid points can also be plotted with references and identity noted on chart. These options may be selected in any combination. For engineers who are responsible for following tool development trials, a material data sheet generator is also included. Used in combination with the FLD charts the material data sheet would allow the material used at each tool show to be fully characterized. The entire system would be very useful to any engineer involved in formability analysis and tool development.
