Out-Of-Plane stress intensification factor for Miter Bends

[ir KW Radder]

Shaswin,

Your conclusion is not quite correct. In general the bending of the mitre bend will not be completely out-of-plane but a mixture between in-plane and out-of-plane. In that case applying an additional factor 0.8333 (1/1.2) is too favourable. This is justified only in case of a pure out-of plane bending. The user can check the bending direction of a bend in table CSLOAD, but it may be a tedious work to investigate if it concerns an out-of-plane bending, especially for sleeping bends.
