However, inherent to plastic forming is the nucleation and growth of defects, whose detrimental effects on the material behaviour can be described by continuum damage models and eventually lead to material failure. As the damage evolution strongly depends on the stress state, a stress-state-dependent model is utilised to correctly track the accumulation. To formulate and parameterise this model, besides classical experiments, so-called modified punch tests are also integrated herein to enhance the calibration of the failure model by capturing a larger range of stress states and metal-forming-specific loading conditions. Moreover, when highly ductile materials are considered, such as the dual-phase steel HCT590X and the aluminium alloy EN AW-6014 T4 investigated here, strong necking and localisation might occur prior to fracture. This can alter the stress state and affect the actual strain at failure. This influence is captured by coupling plasticity and damage to incorporate the damage-induced softening effect. Its relative importance is shown by conducting inverse parameter identifications to determine damage and failure parameters for both mentioned ductile metals based on up to 12 different experiments.</jats:p>"}],"language":[{"iso":"eng"}],"keyword":["ductile damage","stress-state dependency","failure","parameter identification","punch test","clinching"],"issue":"4","year":"2024","date_created":"2025-01-31T16:59:13Z","publisher":"MDPI AG","title":"Material Parameter Identification for a Stress-State-Dependent Ductile Damage and Failure Model Applied to Clinch Joining"},{"type":"journal_article","status":"public","department":[{"_id":"157"}],"user_id":"71269","_id":"27186","article_type":"original","publication_identifier":{"issn":["1350-6307"]},"publication_status":"published","intvolume":"       136","citation":{"ama":"Otroshi M, Meschut G.
