Abstract :

Today, engine failures are rare but they are always possible despite the high engine reliability. These failures can result from a defect in cooling, a storage problem or maintenance. Premature wear of a mechanical part and sometimes bad conditions of use of the driver the engines are not always immune to failure (ignition, power, defaulters accessories such as connecting rod, crankshaft etc ... pieces that form the central part of the mechanics of the engine, and are normally solicited by various thermomechanical efforts (stress, compression, bending, expansion ...). In this context, we conducted an analytical and numerical Comparative study of resistance to thermo&amp;ndash;mechanical fatigue concerning two connecting rods forged by the two most often used techniques in the world, namely the metal powder forged and forged steel C70. The connecting rods are submitted to mechanical forces of compression pressure, and the effect of heat of combustion. The extraction of the stresses, strains and displacements using the computer code Castem based on finite element method allows us to classify materials according to the two most reliable
