DNVGL RP C203 Mean Stress Factor

Calculate DNVGL-RP-C203 mean stress factor for materials with insignificant residual stress.

A stress reduction factor can be applied when the stress range is partly or wholly compressive. The reduction factor is not valid if there are significant residual stresses.

CALCULATOR : DNVGL RP C203 Section 2.5 Mean Stress [FREE]   ±

Calculate mean stress reduction factor for compressive loading (DNVGL-RP-C203 section 2.5).

The reduction factor can be applied to non welded material such as cutouts where the stress range includes compressive (negative) stress. The reduction factor should not be used for welds, or in other cases where there are residual stresses.
