Fatigue life prediction of butt weld joint with weld defects at multiple locations
Ebron Shaji Gnanasigamony Thankareathenam, Prabhu Raja Venugopal, Gautham Velayudhan, Mohanraj Selvakumar
Izvirni znanstveni članek
Oznake: butt joint;weld defects;fatigue loading;fatigue life;
A numerical model developed using finite element software is used to determine the fatigue life of an arc-welded butt joint with weld defects: lack of penetration, lack of fusion, and undercut, which occur predominantly in welded structures. High-strength, tempered, and quenched fine grain ASTM A517 ...

The roof slab of a nuclear reactor supports all the components and sub-systems. It needs to resist the seismic loads in accordance with load-carrying criteria. The static stress analysis of the reactor roof slab reveals that high-stress concentration was present in the pump penetration shell (PPS) t ...
