Purpose and goal

The goal of the project is to create a complete multi-physics platform for simulation of thermo-mechanical forming that takes into account tool wear.

Results and expected effects

Predictive process models for thermo-mechanical forming processes like press hardening have been developed during this project. Simulative, tribological experiments were carried out on uncoated and surface treated/coated tool steel materials sliding against uncoated and Al-Si coated 22MnB5 steel. The results were used to propose two modified Archard wear models in which the wear coefficient was set as a function of temperature, pressure and sliding velocity. The two tool wear models were implemented in the finite element (FE) simulations.

Approach and implementation

The interdisciplinary research tasks were accomplished through close collaboration between the divisions of Mechanics of Solid Materials and Machine Elements at Luleå Univeristy of Technology, the employer of press hardening Gestamp Hardtech, the tool steel supplier SSAB and the surface coating companies Oerlikon Balzers Sandvik AB and Ionbond Sweden AB as well as the research institute Swerea Mefos.
