Abstract Scope |
Additive Manufacturing (AM) offers enhanced flexibility of design for complex engineered components, enabling the fabrication of geometries otherwise inaccessible to conventional manufacturing processes. Application of AM components for critical applications, however, has largely been limited due to the variability observed in mechanical response and the stochastic nature of failure in these parts. Here we present the application of conventional and three-dimensional (3D) microstructural characterization of samples of AM AlSiMg to validate and improve modelling approaches to predict mechanical response in AM materials. In situ computed tomography (CT) loading experiments reveal the role of defects and surface artifacts inherent to the manufacturing process. Given a well-calibrated material model, a finite element modelling framework can accurately predict failure in these AM parts. The sensitivity of the modelling framework to mesh size, as well as it’s extensibility to larger-scale, real-world components will also be discussed. |
