A review of literature for the structural assessment of mitred bends

The condition of ‘perfect clamping’ is discussed and it is shown that even for a reinforcing ring having a depth equal to one half the cylinders' diameter it is still necessary to make some allowance for radial displacement at the oblique edge. Reasons are suggested for the lack of symmetry in circumferential and axial stress profiles over the range ‘intrados’ to ‘extrados’.
