Numerical and experimental study for AM50 magnesium alloy under dynamic loads
Article
Full-text available
  • Jan 2021
Magnesium alloys are widely used in automotive (steering wheel frames) and aerospace due to their lightweight, ductility, energy absorption and castability properties. Finite Element Analysis and design optimisation have driven the improvement of structural crashworthiness, stiffness, strength, durability, and NVH (noise vibration, harshness) perfo...

... The Charpy test is the most widely used method to evaluate the impact strength of materials. It can be used in various types of materials such as polymers, ceramics, and composites [9][10]. In this study, an Instron CEAST 9050 Charpy test rig with a maximum of 25 J was used to determine the impact strength of the 3D printed specimens. ...
Numerical and Experimental Study for Al4043A Aluminium-Silicium Alloy Fabricated by Wire Arc Additive Manufacturing under Dynamic Tests
Conference Paper
  • Oct 2023
The paper presents an experimental investigation of the impact properties and imperfections of the 3D printed Al4043A aluminium-silicium alloy using wire-arc additive manufacturing. Using an experimental program based on factorial experiments, correlations between the main WAAM process parameters and the related properties of the deposition were determined. Charpy impact strength investigations, using standard notched specimens, were performed on an Instron CEAST 9050 instrumented Charpy impact pendulum system following the ISO 148-1 standard. During the experimental tests, the brittle behaviour of the specimens could be observed. After the experimental tests, the impact behaviour was numerically analysed, showing a relatively good correlation between the results.
