Prediction of compression buckling load and buckling mode of hat-stiffened panels using artificial neural network

•Axial compression tests were conducted on hat-stiffened composite panels and simulated by FE.•Local buckling was observed by strain bifurcation phenomena and full-field deformation.•Training and testing datasets of ANN are constructed by FE model group.•Two ANNs are selected to predict the buckling load and buckling mode respectively.•Performance and generalization ability of ANNs are verified.
