CALC_FATIGUE - with mean stress was created by Yasir Bashir
hello
With POST_FATIGUE mean stress can be considered in a fatigue analysis for just one point.
CALC_FATIGUE has the advantage that it calculates not only for one point, but for the complete model. This is good for making a coloured plot of the whole model.
But the option CORR_SIGM_MOYE ='GERBER' or 'GOODMAN' to take into account the mean stress is included in CALC_FATIGUE only for dynamic fatigue calculation (FATIG_VIBR). I miss it for the much simpler uni-axial static fatigue calculation with CUMUL_DOMAGE
Questions:
(1) why does it not exist for CUMUL_DOMAGE? I suppose it should be very easy to include, and it is very essential to use it
(2) can anybody propose a workaround?
