Calculate DNVGL RP C203 bolt tensile stress amplitude and allowable cycles from tensile load amplitude.
The bolt is assumed to be in tension (the mean stress is ignored). The tension load amplitude is the difference in tension load (compression is ignored). The bolt tensile area can be calculated for either ANSI threads, or ISO threads.
