Stress concentration factors for axial and shear loading applied to short flat bars with projections

Abstract

The finite element method has been used to obtain stress concentration factor data for flat ‘T’ shaped components, subjected to axial and shear loading, with both remote and local restraints being applied. The ratio of length to depth (or slenderness ratio) of the shank region is generally less than 3:1. For these short components under shear (or bending) loads, primary bending stresses are no longer dominant and transverse shear is an important secondary effect.Comparisons are made between the predictions with remote and local restraints in order to quantify the effect of localizing the restraints (or load).
