Abstract
In this thesis, a new traction stress based method for characterizing shear strength is investigated by carrying out a series of shear strength tests. The AWS method for the calculation of shear strength shows significant discrepancies between longitudinal and transverse specimens. The main purpose of this new traction based definition for shear strength is to demonstrate that there exists a single shear strength value regardless of specimen geometry and loading conditions. With this new approach a better correlation between shear strength values for transverse and longitudinal specimens is achieved. Special issues occur with the multi-pass welds in regards to the failure angle. The AWS equation does not account to different failure angles of the specimens, it only assumes 45o failure angle in all the cases, but the new approach takes into account the different failure angles. Finally with this method a quantitative weld sizing can be achieved for fillet welds.
