Original abstract

The goal of the presented work is to demonstrate a capability of a non-linear computational model for a leading edge morphing based on the geometrically exact Timoshenko beam theory implemented in the finite element method. The leading edge topology is divided into outer surface with various bending and tension response along the element centre line and kinematic mechanism. Their interconnection is realized by joints, in the computational model realized by the Lagrange multiplier technique. Loading is realized by prescribed moment in one mounting node which represents an electric servomotor. In the results section, beam resultants dependent on the various initial configuration of the kinematic mechanism are analysed.
