Appendix A to Part 154—Equivalent Stress
I. Equivalent stress (σ c) is calculated by the following formula or another formula specially approved by the Commandant (CG-522) as equivalent to the following:
σx=total normal stress in “x” direction.
σy=total normal stress in “y” direction.
τxy=total shear stress in “xy” plane.
II. When the static and dynamic stresses are calculated separately, the total stresses in paragraph I are calculated from the following formulae or another formulae specially approved by the Commandant (CG-522) as equivalent to the following:
III. Each dynamic and static stress is determined from its acceleration component and its hull strain component from hull deflection and torsion.
