Background
Friction during metal forming processes is complex and in conventional friction models, such as Coulomb’s law or the constant friction law, not realistically represented. Particularly in sheet metal forming, as employed in the automotive industry for instance, the fact that full contact between tool and workpiece is not necessarily present makes those models not suitable. In order to understand more about how friction evolves throughout sheet forming processes we need to look at the microscopic surface of a metal.

Here, the asperity deformation (flattening) as function of the normal pressure, subsurface deformation, material properties and surface condition is of major interest (Nielsen & Bay, 2018).

In order to take the development of friction models to next level, we aim at an advanced methodology to analyse microscope images. Here, we want to evaluate the real contact area ratio (see picture) of asperities.

Objectives of this project:
This project aims to analyse asperity flattening in real metal surfaces and develop a code or deploy Spip to calculate alpha. The objectives are the following:

• Understand challenges in friction and friction modelling during metal forming operations

• Acquisition of microscope images using the Alicona or Lext

• Application of SPIP to calculate alpha

or

• Development of a code (pref. Matlab) to analyse the images and calculate alpha
