Ongoing projects

•                    2015-2019, KKS Synergy project, - Fatigue and Wear in Manufacturing Industry (project ID 20150090, budget 18.5 Mkr, role – co applicant, research manager of sub-project WEAR). The project is focused on the combined effect of sliding wear and fatigue loading, including impact fatigue loads in severe industrial applications, on materials performance. Partners - Atlas Copco Rock, Sandvik Mining Rock Tools, Ovako Steel and Uddeholms AB

•                    2017-2020, EU project AT-LAB - regional additive manufacturing laboratory at Karlstad university, (project ID: 20201144, budget 13.8 Mkr, role – project leader). The project is dealing with development and implementation of a sustainable and resource-efficient additive manufacturing technology – selective laser melting - and is dedicated to networking and research in collaboration with regional manufacturing industry. The project is co-financed by Region Värmland, Karlstad University and European Regional Development Fund.
