Local scale fracture characterization of an advanced structured material manufactured by fused deposition modeling in 3D printing.
Abstract
Additivemanufacturing(AM)isapromisingwaytoproducecomplex structures by adding layers. AM arises great interest both in industrial and academic sectors to develop new advanced structured materials. To benefit from its advantages, it is important to accurately characterize the mechanical properties of the obtained structures in order to ensure their integrity during operation. It becomes important to characterize these structures at the local scale (micron and/or the nanometer scale). In the specific case of polymeric materialsproducedbyFusedDepositionModeling(FDM),the comprehension of the mechanical behavior between adjacent layers during deformationcanhelptoimprovemechanicalproperties.However,few studiesintheliteraturehavefocusedonimplementingapproachesto characterize local strains at the surface of these materials. In this study, an original approach based on the use of a speckle pattern with particles average size of 20 microns in diameter was coupled to digital image correlation (DIC). It has been applied to the case of a SENT structure with a notch made by FDM.Thesuccessiveimagesrecordedbyadigitalmicroscopeallowa qualitative analysis of the evolutions of the local strains. The kinematic fields are obtained by DIC. The strain evolutions at the notch’s tip are highlighted. Thedeformationmechanismsatthelocalscaleareconfrontedwiththe macroscopic behavior of the structure.
