Journal ArticleDOI
Rapid tooling by laser powder deposition : Process simulation using finite element analysis
TL;DR: In this article, a thermo-kinetic LPD model coupling finite element heat transfer calculations with transformation kinetics and quantitative property-structure relationships is presented. And the results show that the thermal history and, hence, the microstructure and properties of the final part depend significantly on these parameters.
Study of the influence of 3D printing parameters on the mechanical properties of PLA
TL;DR: In this paper, the influence of 3D printing parameters, such as Infill Density, Extrusion Temperature, Raster Angle and Layer Thickness, on mechanical properties, namely Ultimate Tensile Strength, Yield Strength, Modulus of Elasticity and Elongation at Break, after it goes through the manufacturing process was determined.
Journal ArticleDOI
The effect of geometry on the flexural properties of cellular core structures
TL;DR: Composite sandwich materials are very common in structural uses for a wide range of applications in the aerospace and automotive industry that require low weight, high bending strength, and high ensembles as discussed by the authors.
Journal ArticleDOI
Tuneable micro- and nano-periodic structures in a free-standing flexible urethane/urea elastomer film
Maria Helena Godinho,A. C. Trindade,João L. Figueirinhas,João L. Figueirinhas,L.V. Melo,Pedro Brogueira,A.M. Deus,Paulo Ivo Cortez Teixeira +7 more
TL;DR: Results are interpreted by assuming the film to consist of a thin, stiff surface layer lying atop a thicker, softer substrate (“bulk”) and the skin's higher stiffness is hypothesised to be due to the more extensive cross-linking of chains located near the surface by the UV radiation.
Journal ArticleDOI
Simulation of Phase Transformations in Steel Parts Produced by Laser Powder Deposition
TL;DR: In this paper, a three-dimensional thermo-kinetic finite element model of laser powder deposition of tool steels was developed for the study of the influence of substrate size on the microstructure and properties of a six-layer wall of AISI 420 tool steel.
