The shape optimisation of a connecting rod with fatigue life constraint

International Journal of Materials and Product Technology (IJMPT), Vol. 11, No. 5/6, 1996

Abstract: This paper presents a deterministic approach, considering the fatigue life requirement, in the optimal design of a connecting rod for a newly developed motor-cycle engine. The main idea is to use the finite element method to calculate the stresses upon the connecting rod, and to use sound fracture mechanics theorems, along with material fatigue properties, to calculate fatigue life during the optimisation process. The life requirement is treated as a side constraint, and the volume of the of the connecting rod as the objective function.
