Journal ArticleDOI
Mechanical property characterization and simulation of fused deposition modeling Polycarbonate parts
Miquel Domingo-Espin,J. M. Puigoriol-Forcada,A.A. García-Granada,Jordi Llumà,Salvador Borrós,Guillermo Reyes +5 more
TL;DR: In this article, a finite element analysis (FEA) simulation with physical testing was used to determine the stiffness matrix of an orthotropic material, including three Young's modulus, three Poisson's ratio and three shear modulus.
Journal ArticleDOI
Mechanical Properties of 3D-Printing Polylactic Acid Parts subjected to Bending Stress and Fatigue Testing
J. Antonio Travieso-Rodriguez,Ramón Jerez-Mesa,Jordi Llumà,Oriol Traver-Ramos,Giovanni Gómez-Gras,Joan Josep Roa Rovira +5 more
TL;DR: Results show that layer orientation is the most influential parameter, followed by layer height, filament width, and printing velocity, whereas the fill density and infill pattern show no significant influence.
Journal ArticleDOI
Finite Element Analysis of Ball Burnishing on Ball-End Milled Surfaces Considering Their Original Topology and Residual Stress
TL;DR: In this article, the authors developed a 3D numerical finite element model of the ball burnishing process including in the target workpiece real surface integrity descriptors resulting from a ball-end milled AISI 1038 surface.
Journal ArticleDOI
Comparative study of the flexural properties of ABS, PLA and a PLA–wood composite manufactured through fused filament fabrication
TL;DR: In this paper, the authors analyzed the mechanical properties of acrylonitrile-butadiene-styrene (ABS) parts manufactured through fused filament fabrication and compared these results to analogous ones obtained on polylactic acid (PLA) and PLA-wood specimens to contribute for a wider understanding of the different materials used for additive manufacturing.
Journal ArticleDOI
Superficial Effects of Ball Burnishing on TRIP Steel AISI 301LN Sheets
TL;DR: In this article, the consequences of applying an ultrasonic vibration-assisted ball burnishing process and its non-vibration assisted version on the topology and subsurface microstructure of a transformation-induced plasticity AISI 301LN alloy were explored.
