WebbWith a share of approximately 80%, the connecting rod shaft is mainly loaded by dynamically acting compression stresses out of the combustion process. The remaining 20% are dynamically acting bending loads. This results in a very complicate stress profile in the connecting rod eye (or small end) while engine operation.
