TidGen MHK Generator Composite Fatigue Analysis Procedure

A procedure was described for performing a fatigue analysis of composite foils for an MHK generator. The steps included generating load data, S-N (Stress versus Number of cycles to failure) diagrams through fatigue testing, cycle counts, damage versus load, and cumulative damage. An illustrative analysis was then performed using representative S-N data.
