METHOD FOR EVALUATING THE EFFECT OF AN ELECTRIC DISCHARGE ON A 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 damage 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 elements the material of the aircraft structure; calculating the intensities running through the electric mesh of the material of the aircraft structure from the intensity introduced in the generators; calculating with the previous intensities the heat which is dissipated in each of the elements of the electric mesh of the material of the aircraft structure; calculating the distribution of temperatures in each of the elements of the electric mesh of the material 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 distribution 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.
