C7 - Wear

Mechanism-based Modeling of Wear in Sheet-Bulk Metal Forming

Project Status: finished

Last Update: 09.10.2020


The aim of the project is a modelling of tool-surface wear in sheet-bulk metal forming operations. These tool surfaces are sometimes treated for an optimisation of the friction behaviour by microstructuring. Thus, the simulation of wear of these microstructures is a simulation problem on the mesoscale. The shape of the microstructuring is geometrically resolved in the model, whereas the surface roughness is represented by a suitable friction model.

Two modelling approaches are pursued in the project. The first approach consists of using the commercial finite element program Abaqus to simulate the contact and forming problem. The local surface tractions and relative velocities are then evaluated in a Python-based postprocessor and used to determine local wear volumes according to the Archard model. The wear volumes are applied by adapting the surface mesh and a new mesh is created. The simulation of a tool passover and the schematic representation of the surface adaptation are shown in the following figures.

The second approach provides mechanism-based wear modelling. The Particle Finite Element Method is suitable for simulating the removal of surface particles or micro chips. For this purpose, the tools and workpieces under consideration are seen as particle clouds of material points. A repeated re-meshing and shape detection of the body is performed. The finite element meshes are a means of calculating the continuum represented by the particle cloud. However, history variables as well as the deformation history are stored on the particles. The shape recognition allows new surfaces to be formed and chips or particles to be separated when high local deformations occur. Due to the fundamental changes to be incorporated in the finite element equations, a fully accessible implementation is necessary and the use of commercial finite element software is not practical. Thus, the adequate contact simulation moves into the focus of the modelling, as it is the basis for a robust and accurate simulation of the removal processes. Here the Particle Finite Element Method includes algorithms which are also suitable for the discretisation of the contact surfaces. The material removal itself depends on the parameters of the shape recognition algorithms, but also essentially on the local friction and material properties. Thus, the influence of the local mechanisms leading to material removal can be investigated on the presented simulation model. The following figure shows the contact simulation of a tool-body drawn over a soft block, as well as a notched tensile specimen, where the material separation is initiated by the shape recognition algorithm.
