Method Studied on the Tensile and Compression Strength Prediction of Friction Stir Welding Aircraft Panel

摘要

The tensile and compression strength of the Z shaped stiffened-welded plate is studied in this paper. Through the analysis of the main influential factors of the panel strength, the theoretical calculation formula of the tensile and compression strength of the panel plate which are verified by the experimental values is established in this paper,. And the tensile strength prediction value is 8.4% larger than the experimental value while the compression strength prediction value is 4.36% smaller than the experimental value. This method can provide reference for the selection of welding structure.
