Влияние параметров предварительного обжатия материала в зоне отверстия на усталостную долговечность элементов авиационных конструкций

摘要

The fatigue life prediction method is proposed for aircraft structural elements with materialpre-compression in the area near the hole. The experimental verification of the proposed method isperformed. A satisfactory matching between the calculated and experimental data is ensured. Theanalysis of the compression parameters effect on the structural elements fatigue life is provided.
