Fatigue Behaviour of Synthetic Nodular Cast Irons
A. Vaško, L. Trško, R. Konečná, Faculty of Mechanical Engineering, University of Žilina, Žilina, Slovak Republic The paper shows the influence of charge composition on microstructure, fatigue properties and failure micromechanisms of nodular cast irons. The additive of metallurgical silicon carbide (SiC) in analysed specimens increases the content of ferrite in the matrix, decreases the size of...
متن کاملFailure 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 ...
متن کاملFatigue Performance of Forged Steel and Ductile Cast Iron Crankshafts
Fatigue is the primary cause of failure of crankshafts in internal combustion engines. The cyclic loading conditions and the stress concentrations in the crank pin fillets are unavoidable, and can result in fatigue failure. The objectives of this study were to compare the fatigue behavior of forged steel and ductile iron crankshafts from a one-cylinder engine as well as to determine if the fati...
متن کاملModeling of Ultrasonic Testing for Inspection of Nodular Cast Iron Insert
Nodular cast iron insert will be used as the inner component of nuclear fuel disposal canister. The outer cover of the canister is copper tube of 50 mm nominal thickness. Nodular cast iron insert is cast around several steel channels, which also strengthen the structure. The mechanical properties of the cast iron insert will be tested according EN-1563 /1/. According the specifications 100% NDT...
