A FORTRAN program had been established to read ANSYS binary result file promptly. Based on ORE B12/RP17, multiaxialstress status was transformed to uniaxial stress status, and the maximum stress, minimum stress, mean stress and stress amplitude withunit or node direction stress were calculated; then, the fatigue strength of structure was evaluated based on Goodman curve about Haigh style;finally, calculated results were written into original ANSYS result file, and the fatigue strength results could be displayed by ANSYS generalpost process, with which, visualization of structure strength and its displaying had been achieved.
