Characterisation of Diffuse and Local Necking of Aluminium Alloy Sheets using DIC Technique
Journal Title: Acta Technica Jaurinensis - Year 2019, Vol 12, Issue 3
Abstract
This paper introduces a new method for the characterisation of the boundary of diffuse and local necking based on DIC measurements during tensile tests. A series of images illustrate the extension of diffuse necking and show the occurrence of local necking as well. The evaluation of strain distribution gives the exact description of processes using both time dependent and non-dependent methods.
