The article provides an overview of methods for assessing fatigue strength of basic parts of piston engines. It considers the techniques such as deterministic, statistical and dislocation approach. Deterministic and statistical methods of calculation require a large amount of experimental data, or set a large margin, which leads to unreasonable waste of material and overweight details. Potentially, the dislocation approach allows determine a more accurate damageability of items in different locations, which have different stress-strain state.
