.... The hub of the wheel had sheared off. Parallel to the fracture surface, there was circumferential cracking near the fillet of the flange. The crack had proceeded from the outer surface at the fillet to the inner. Fractography revealed cleavage mode. The rim had failed due to excessive pressure of air...
