Fracture locus of additively manufactured AlSi10Mg alloy

Krishna Prasath Logakannan et al.

Summary: Fracture occurs in cellular structures due to localized complex stress and/or strain state, making it difficult to accurately predict failure using traditional testing methods and finite element analysis. The build orientation of different ligaments also significantly affects the macroscopic performance of cellular structures. In order to improve numerical predictions, the failure strain should be considered in relation to stress triaxiality and build orientation. Experimental determination of fracture loci in AlSi10Mg alloy fabricated using Laser Powder Bed Fusion (LPBF) for different build orientations helps in developing predictive capabilities. Numerical models considering triaxial fracture loci provide more accurate predictions of deformation mode and fracture location in re-entrant structures compared to models that assume simple uniaxial tensile failure.

Digital Light Processing of 2D Lattice Composites for Tunable Self-Sensing and Mechanical Performance

Omar Waqas Saadi et al.

Summary: This study investigates the self-sensing performance of additive manufacturing-enabled 2D nanocomposite lattices under different loading conditions. The results show that the piezoresistive sensitivity of the lattices varies with their architectural design and relative density. The findings provide valuable insights into the design of strain sensors and lightweight structures.

Synthesis and Characterization of Carbon Nanotube-Doped Thermoplastic Nanocomposites for the Additive Manufacturing of Self-Sensing Piezoresistive Materials

Pawan Verma et al.

Summary: This study presents carbon nanotube-reinforced polypropylene random copolymer nanocomposites for the additive manufacturing of self-sensing piezoresistive materials. It is found that the addition of carbon nanotubes enhances the crystallinity, stiffness, and strength of the printed parts. Furthermore, the nanocomposites demonstrate multifunctional in situ strain and damage sensing due to the electrical conductivity imparted by the carbon nanotube network.

Energy absorption characteristics of additively manufactured plate-lattices under low- velocity impact loading

J. Jefferson Andrew et al.

Summary: This study focuses on the low-velocity impact response of 3D plate-lattices fabricated via stereolithography additive manufacturing. The hybrid lattices were found to attenuate peak impact stress and extend load pulse duration, leading to higher toughness and energy absorption capacity. The distribution of plates in each elementary structure in hybrid configuration plays a crucial role in transforming brittle mode fracture into progressive damage of the plate-lattices.
