A Newly Observed Pattern of Imperfect Graphite Spherulite in Nodular Iron

Failure Analysis of a Four Cylinder Diesel Engine Crankshaft Made From Nodular Cast Iron

The premature breakage in some four cylinder diesel engine crankshafts was reported. All crankshafts were failed from the same region. Failures had occurred in the first crankpin, the nearest crankpin to the flywheel. Dynamic analysis and finite element modelling were carried out to determine the state of stress in the crankshaft. FEM results revealed that the first crankpin fillet is the most ...
