Failure test and finite element analysis of typical aircraft joints
To check the strength of the typical lug joints on ailerons of a certain type of aircraft,the finite element nonlinear failure analysis is carried out using Johnson-Cook plastic constitutive model.The failure load and failure mode of the joint are computed,and compared and verified with the test results.The relative error between the analysis results and the experimental results is within 5％,the failure mode is completely consistent with the test.The accuracy and effectiveness of the method is verified.
