Original Abstract

The article describes results of experimental investigation and computer modelling of crack growth in integrally stiffened test panels high-speed milled from 2024 alloy plate. Data necessary for modelling were achieved by testing of coupons on constant and flight-simulation cyclic loading. Residual stresses after machining were meas-ured using strain gauge method. Integral panels were tested under constant amplitude loading with two values of amplitude and R and also under flight-simulation cyclic loading. Results of testing are compared with calculated cracks propagation curves. The comparison shows good correlation.
