Measurements in Circumferential and Meridian Direction

Measuring lengths to be applied

l_{g x} = 4 \sqrt{r \cdot t}

l_{g w} = 25 \cdot t o d e r l_{g w} = 25 \cdot t_{m i n} m i t l_{g w} \leq 500 m m

l_{g θ} = 2, 3 \cdot {({l_{s}}^{2} r t)}^{0, 25}, a b e r l_{g θ} \leq r

r	Shell radius
t	Shell thickness
t_min	Thickness of the thinner plate at the weld
l_gx	Measurement for significant compressive stresses in the meridian direction that need to be calculated in both the meridian and the circumferential direction
l_gw	Measurements that need to be calculated when the ratio between the shell radius and the thickness is less than r/t =400
l_gθ	Measurements that need to be calculated for significant compressive stresses in the circumferential direction or in-plane shear stresses in the circumferential direction
l_s	Length of the shell segment in the meridian direction between edges assigned to either BC1 or BC2
