METHOD AND DEVICE FOR DIGITAL RECONSTRUCTION OF AN ELEMENTARY VOLUME REPRESENTATIVE OF A MICROSTRUCTURE OF COMPOSITE MATERIAL

摘要

The method comprises: - the definition (F10) of an elementary volume; the filling of the volume with digital elements modeling fiber elements of the composite material, and extending longitudinally along a main axis, comprising: the association (F30) with each element of a position in a plane of the space and an orientation of its main axis; and ○ the successive positioning of each element in the volume, in accordance with the position and the orientation which have been associated with it, this positioning comprising a contacting (F40) of the element with at least one wall of the elementary volume and / or at least one previously positioned element, and a geometric adaptation (F50) of the element to said at least one wall and / or said at least one previously positioned digital element with which it is brought into contact, at least one portion of an element used to fill the volume undergoing, during the geometric adaptation, a deformation other than an inclination of its longitudinal axis with respect to the main axis of this element.
