ANALYTICAL METHOD FOR LIMIT LOAD CAPACITY CALCULATION OF THIN WALLED AIRCRAFT STRUCTURES

摘要

The paper is focused on description and comparison of different methods for limit load capacity calculation of thin -walled aircraft structures - considering all possible forms of buckling and failures on nonlinear behavior of the structure under gradually increased loading. Methods considered include: finite element method (FEM), reduction coefficients method and special attention is given to so called "gradually increased loading method" -GILM (original method developed by the author of this paper).
