XA_ etc Stresses in Thin Shells Derived from Force and Moment Resultants
XA_ etc Stresses in thin shells derived from force and moment resultants
The force/moment resultants are converted to local axial and bending stresses as follows:
| Axial stress | = | F/t |
| Bending stress | = | 6M/t 2 |
| Outer fibre stress | = | F/t +/- 6M/t 2 |
| Where: |
F = force / unit width M = moment / unit width t = section thickness |
Note that the bending component here assumes a linear elastic stress distribution (ie stress = My/I ) so "bending" and "outer fibre" stresses will be incorrect in a plastic section.
