The release LIMIT2020 includes a new fatigue code: IIW Recommendations (the Recommendations for Fatigue Design of Welded Joints and Components, Second Edition with updates from 2014, International Institute of Welding). The implementation can be used for welded steel and welded aluminium.
Features:
▪ Assessment types for:
− Fatigue against CAFL (Constant Amplitude Fatigue Strength), if no cycle numbers are given
− Constant amplitude fatigue for (very) high load cycle numbers
− Variable amplitude fatigue
− Static strength
▪ Can take into account:
− Proportional or un-correlated loads
− Thickness correction
− Elevated temperatures
− Mean stress influence
− Toe improvement by grinding or TIG dressing
▪ SN-curves can be modified by user
