Solving equations of thin-walled multistringer torsion box design in view of geometrical non-linearity

Abstract

A procedure of thin-walled multistringer torsion box design in view of geometrical non-linearity is proposed. Initial non-linear relations are linearized by the successive loading method. Solving equations are obtained by using the Lagrange principle; these are presented in the form of a boundary problem for a system of ordinary linear differential equations.
