Abstract
This thesis focuses on conducting a numerical study to examine the flexure behaviours of Aluminium 5052-H32 alloy subjected to different strain rates. Aluminium alloys are widely used in structural applications due to their favourable
combination of strength, lightweight properties, and excellent formability. Understanding the response of these alloys to different loading conditions, particularly strain rates, is crucial for ensuring their optimal performance and structural
integrity.The objective of this research is to investigate and analyse the flexural characteristics of Aluminium 5052-H32 alloy under varying strain rates. Flexural behaviours refers to the response of a material when subjected to bending loads, which is of great importance in structural applications. By subjecting the alloy to different strain rates, ranging from quasi-static to high strain rates, the thesis aims to explore the influence of strain rate on the flexural properties, including stiffness, strength, and failure behaviours. To achieve the research goals, a numerical approach will be employed using finite element analysis (FEA). FEA allows for the simulation of complex loading conditions and provides valuable insights into the material's behaviours. The thesis will involve creating a finite element model of the Aluminium 5052-H32 alloy and subjecting it to various bending scenarios at different strain rates. The simulations will consider the material's anisotropic behaviours, incorporating its inherent microstructural features and mechanical properties. Furthermore, the thesis will examine the microstructural changes and deformation mechanisms that occur within the aluminium 5052-H32 alloy under different strain rates. This will involve analysing the distribution of stresses, strains, and deformation patterns within the material. The results will be compared and evaluated to identify any strain rate dependent trends or anomalies in the flexural behaviours of the alloy.
