IIW recommendations

In this paper, the hot spot stress approach recommended by the International Institute of Welding (IIW) has been applied to estimate fatigue life of fillet welded structures for the chassis frame of semi trailer, which was locally manufactured in Vietnam. The combined method of the finite element analysis (FEA) and the multi-body dynamic simulation (MBDS) is proposed for structural analysis.

Weld toe improvement methods have been widely investigated and have, in most cases, been found to give substantial increases in fatigue strength. However, there are large variations in the actual improvements achieved, and the results obtained by various methods are not always ranked in a consistent manner. One explanation for the observed varia tions is the lack of standardization of the optimum method of application, but variations in the material, type of loading and type of weld detail may also have influenced the results.
