Method for determining a deformation of an area of a part obtained by additive manufacturing

Abstract

The method is for the discriminant monitoring of a composite multi-material assembly (1) having at least one internal layer (10) made of a first, electrically conductive composite material and a second layer (11) made of a second, electrically insulating composite material, the second layer (11) covering the first internal layer (10). The method includes: —preparing the composite multi-material assembly (1) by exposing a portion (101) of the internal layer (10), which constitutes a first electrode; —applying a second electrode (103) to the surface of the second layer (11), one of these electrodes (103) being earthed; —performing discriminant monitoring wherein a current is generated between the first electrode (101) and the second electrode (103) by applying a threshold voltage Us predetermined by calibration to characterize a lack of structural defects, the appearance of a breakdown at a voltage lower than the threshold voltage Us being indicative of the presence of at least one structural defect in the composite assembly (1).
