METHOD FOR EVALUATING THE EFFECT OF AN ELECTRIC DISCHARGE ONA COMPOSITE MATERIAL

摘要

The present invention relates to a method for evaluating the effect of an electric discharge on an aircraft structure through the evaluation of the d amage caused by the effect of the thermal heating generated by the mentioned discharge on the structure, comprising the steps of : applying an electric discharge on the material of the aircraft structure by means of an intensity generator; distributing in an electric mesh with resistive electric element s the material of the aircraft structure; calculating the intensities runnin g through the electric mesh of the material of the aircraft structure from t he intensity introduced in the generators; calculating with the previous int ensities the heat which is dissipated in each of the elements of the electri c mesh of the material of the aircraft structure; calculating the distributi on of temperatures in each of the elements of the electric mesh of the mater ial of the aircraft structure; determining the elements of the electric mesh of the material of the aircraft structure which, due to the effect of the d istribution of temperatures, experience a change of state and evaporate; and determining the damage caused to the material of the aircraft structure due to the effect of the electric discharge.
