Образование и распространение усталостных трещин в образцах с множественными концентраторами

Abstract

In this work test procedure of specimens with multiple holes made of aluminum alloy D16АТ is considered for multiple site damage assessment. Special methodology for fatigue cracks initiation and propagation registration is developed. According to experimental data kinetic diagrams of fatigue crack propagation are obtained. Crack propagation rate and number of cycles up to estimated length crack formation are defined
