– do not contain data
– can be saved as a .flo file
– seven predefined processes are .flo files
• Data flows through the process
– time series, histograms, FE results, etc.
• DesignLife database file (.fdb file) contains process and data
– saved and archived with WB project

Customer Training Material Load Mapping
• Load mapping converts FE results into stress/strain histories for use
in fatigue calculations
– FE analysis provides results for distinct sets of loads
– load mapping determines how the stresses/strains vary
• fatigue life is controlled by cyclic stresses
• Constant Amplitude, Time Series, and Time Step are common load
mappings used with both stress-life and strain-life fatigue
– constant amplitude loading
• stresses/strains are assumed to cycle between minimum maximum values
– time series loading
• stress/strains are paired with time series loading channels to generate
stress/strain histories
– time step loading
• FE stresses/strains are used directly
