Abstract

Abstract: The axial compression buckling and post buckling characteristics of variable thickness composite stiffened plates are experimentally studied. The bearing capacity of the plate is calculated and analyzed by the engineering analysis method, eigenvalue buckling method, piecewise post buckling method and progressive damage failure method, and then the calculation results are compared with the test results. The results show that it is more reasonable to simplify the support of variable thickness composite stiffened plate stringer to fixed support than to simple support. The error between the calculated value and the experimental value is -13.9%. By introducing the concept of reduced width, the influence of the stiffness of the variable thickness region of the stiffened plate on the buckling characteristics of the skin can be effectively considered, and the accuracy of the engineering analysis method of the variable thickness stiffened plate can be further improved. The piecewise post buckling method and the simulation failure model considering the local effect and transverse stress component can accurately predict the post buckling capacity of variable thickness stiffened plates, with errors of 7.1% and 5.9%, respectively. The post buckling capacity is about 1.27 times of the initial buckling load, indicating that the variable thickness stiffened plate still has a certain post buckling capacity after buckling.

Key words: composite material, stiffened plate with variable thickness, axial compression, buckling, post-buckling, bearing capacity
