Procedure 7-5 Stresses in Spherical Shells from External Local Loads

Procedure 7-5 Stresses in Spherical Shells from External Local Loads [11-13] 

To calculate stress due to radial load (Pj.), and/or moment (M), on a spherical shell or head  

Calculate value S to find stresses at distance x from centerline or value U at edge of attachment. Note At edge of attachment, S = U. Normally stress there will govern. 

Compute stresses in Table 7-15. These stresses are entered into Table 7-16 based on the type of stress (membrane or bending) and the type of load that produced that stress (radial load or moment). 

Stresses in Table 7-16 are added vertically to total at bottom.
