This study introduces a 2D numerical model that circumvents direct contact modeling by applying a slip condition at the sheet interface, significantly reducing computational demands.

This work presents a numerical uniform corrosion model that predicts the corrosion rate of hot-dip zinc in salt-spray environments by incorporating electrochemical reactions, mass transport via the Nernst–Planck equation, and ionic-strength effects through the Brønsted–Bjerrum relation. The model is calibrated using immersion-test data and extended to account for electrolyte layer growth, droplet deposition, and periodic run-off in salt-spray environments. The calibration establishes a relationship between the porosity of the zinc oxide layer and the rate constant of zinc oxide precipitation. The validated model reproduces the transition from activation- to diffusion-controlled corrosion and captures the experimentally observed corrosion kinetics with an error margin of 20% when electrolyte renewal is included. The results highlight the decisive role of electrolyte dynamics in salt-spray environments and provide a foundation for extending the framework to more complex cyclic corrosion tests.</jats:p>","lang":"eng"}],"user_id":"114741","_id":"64250","project":[{"_id":"142","name":"TRR 285 - Subproject B03"},{"name":"TRR 285 - Project Area B","_id":"132"},{"_id":"130","name":"TRR 285:  Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten"}],"language":[{"iso":"eng"}],"publication_identifier":{"issn":["2397-2106"]},"publication_status":"published","citation":{"apa":"Chen, C., Hofmann, M., &#38; Wallmersperger, T.

Recent research indicates that galvanic corrosion can actually enhance the fatigue life of clinched joints. It is then of significant interest to investigate the effects of another corrosion phenomenon, pitting corrosion, on the fatigue behavior of clinched joints. Pitting corrosion occurs in passive metals and can lead to stress concentrations. In the present study, the effects of pitting corrosion are investigated by using Lemaitre’s two-scale fatigue model with a 2D geometry of clinched joints. A slip condition is applied as a boundary condition to simplify the clinched joint model and reduce the computational cost of solving the contact mechanics problem. Additionally, a method to determine the damage strength and the damage exponent used in the two-scale damage model is introduced. Numerical simulations reveal that pitting corrosion reduces the fatigue life of clinched joints, particularly when it occurs on the internal surface in the neck area.</jats:p>","lang":"eng"}],"status":"public","publication":"Acta Mechanica","type":"journal_article","language":[{"iso":"eng"}],"_id":"61161","project":[{"_id":"142","name":"TRR 285 - Subproject B03"},{"_id":"132","name":"TRR 285 - Project Area B"},{"name":"TRR 285:  Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten","_id":"130"}],"user_id":"114741","year":"2025","citation":{"apa":"Chen, C., Harzheim, S., Hofmann, M., &#38; Wallmersperger, T.

These joints are usually weak spots. Here, corrosion and fatigue are decisive influencing factors for the assessment of the service life of such joints. Corrosion generally leads to material deterioration and thus to premature failure of the joints. Under certain circumstances, however, corrosion can lead to an increased fatigue life. While this effect has not yet been fully understood, the present work provides a possible explanation and a modeling approach to predict the fatigue life of precorroded clinched joints. The increased fatigue life is observed when the clinched components are briefly (up to 3 weeks) exposed to a salt spray environment. During this time, a small layer of corrosion products protrudes from the metal surface and fills the gaps between the joined sheets. Due to the increased contact area, the mechanical stress in the joint decreases, resulting in an improved fatigue performance. Although there are a variety of corrosion phenomena, for example, pitting, intergranular, and transgranular corrosion as well as galvanic corrosion, experimental studies indicate that galvanic corrosion is the main contributor of this effect. In the present work, a coupled electro‐chemo‐mechanical corrosion model is presented and applied to two test cases.

In this\r\nrespect, the use of hybrid structures, made of dissimilar materials offers many advantages. However, such hybrid\r\nstructures often have undesirable side effects. For example, brittle intermetallic phases are formed when\r\naluminum and steel are welded. Clinching as a mechanical joining process does not produce such intermetallic\r\nphases since the connection is realized through form and force closure. In this process, a punch passes through\r\ntwo or more sheets and forms them into a permanent joint in a die. In the present work, the corrosion phenomena\r\nof an aluminum-steel clinched joint have been investigated by both experiments and numerical simulations in\r\norder to explain the superior fatigue behavior of pre-corroded joints. Therefore, the clinched joints have been\r\ncorroded by a three-week salt-spray test. In addition, the electric potential and the von Mises stress are calculated\r\nunder the assumption of a static loading. The results of both experiments and numerical simulations can explain\r\nthe improvement in the fatigue behavior of the corroded specimens. This phenomenon can be attributed to the\r\naccumulation of corrosion products in small gaps between the joined metal sheets.","lang":"eng"}],"date_created":"2022-12-06T19:29:59Z","publisher":"Elsevier BV","title":"Corrosion Phenomena and Fatigue Behavior of Clinched Joints: Numerical and Experimental Investigations","year":"2022","department":[{"_id":"630"}],"user_id":"14931","_id":"34253","project":[{"grant_number":"418701707","name":"TRR 285: TRR 285","_id":"130"},{"_id":"132","name":"TRR 285 - B: TRR 285 - Project Area B"},{"name":"TRR 285 – B02: TRR 285 - Subproject B02","_id":"141"},{"_id":"142","name":"TRR 285 – B03: TRR 285 - Subproject B03"}],"article_number":"100130","type":"journal_article","status":"public","volume":6,"author":[{"full_name":"Harzheim, Sven","last_name":"Harzheim","first_name":"Sven"},{"first_name":"Lars","full_name":"Ewenz, Lars","last_name":"Ewenz"},{"first_name":"Martina","last_name":"Zimmermann","full_name":"Zimmermann, Martina"},{"last_name":"Wallmersperger","full_name":"Wallmersperger, Thomas","first_name":"Thomas"}],"date_updated":"2023-01-02T11:04:06Z","oa":"1","doi":"10.1016/j.jajp.2022.100130","main_file_link":[{"open_access":"1","url":"https://www.sciencedirect.com/science/article/pii/S2666330922000346?via%3Dihub"}],"publication_identifier":{"issn":["2666-3309"]},"publication_status":"published","intvolume":"         6","citation":{"ama":"Harzheim S, Ewenz L, Zimmermann M, Wallmersperger T.

The demand for precise predictions increases with the desire of lightweight design in transportation due to environmental protection. Corrosion with its manifold of mechanisms often occurs together with the production of hydrogen by electrochemical reactions. Hydrogen embrittlement is one of the most feared damage mechanisms for metal constructions often leading to early and unexpected failure. Until now, predictions are mostly based on costly experiments. Hence, a rational predictive model based on the fundamentals of electrochemistry and damage mechanics has to be developed in order to reduce the costs. In this work, a first model approach based on classical continuum damage mechanics is presented to couple both, the damage induced by the mechanical stress and the hydrogen embrittlement. An elaborated two-scale model based on the selfconsistent theory is applied to describe the mechanical damage due to fatigue. The electrochemical kinetics are elucidated through the Langmuir adsorption isotherm and the diffusion equation to consider the impact of hydrogen embrittlement on the fatigue. The modeling of the mechanism of hydrogen embrittlement defines the progress of damage accumulation due to the electrochemistry. The durability results like the S-N diagram show the influence of hydrogen embrittlement by varying, e.g. the fatigue frequency or the stress ratio."}],"publication":"Material Modeling and Structural Mechanics","type":"book_chapter","language":[{"iso":"eng"}],"keyword":["Hydrogen embrittlement","Fatigue","Continuum damage mechanics","Numerical simulation","Multi-field problem"],"department":[{"_id":"630"}],"user_id":"14931","_id":"34209","project":[{"grant_number":"418701707","name":"TRR 285: TRR 285","_id":"130"},{"name":"TRR 285 - B: TRR 285 - Project Area B","_id":"132"},{"name":"TRR 285 – B03: TRR 285 - Subproject B03","_id":"142"}],"citation":{"ama":"Shi Y, Harzheim S, Hofmann M, Wallmersperger T.

Depending on the corrosion severity, the time until failure of the component varies. On the contrary, a study has shown that certain riveted metal joints, exposed to a short period of mechanical loading and corrosion, have greater fatigue limits. This study gives rise to the question how different corrosion exposure times affect joint metallic components. In the present research, a theoretical approach is developed in order to evaluate the influence of galvanic corrosion on joint integrity of clinched metal joints. At first, the framework for modeling galvanic corrosion is introduced. Furthermore, a simulative investigation of a clinching point is carried out based on the assumption that corrosion leads to a reduction of the contact area which leads to a local increase in contact pressure. For this purpose, the stiffness values of individual elements in a finite element model are reduced locally in the contact area of the undercut and the contact stress along a path is evaluated. Summarizing, a modeling approach is introduced to investigate corrosion effects on load-bearing behavior of clinched joints.

Precise predictions are neccesary for lightweight design in transportation due to environmental protection. During corrosion often hydrogen is produced by electrochemical reactions. Hydrogen embrittlement is one of the most feared damage mechanisms for metal constructions leading to early and unexpected failure. Until now predictions are mostly done through costly experiments. In the present research, a first simple simulation model based on the fundamentals of electrochemistry and continuum damage mechanics is developed to couple the damage induced by the mechanical stress with the hydrogen embrittlement. Results of the durability are presented for the case of uniaxial cyclic loading for varying testing frequency.","lang":"eng"}],"status":"public","project":[{"name":"TRR 285: TRR 285","_id":"130","grant_number":"418701707"},{"name":"TRR 285 - B: TRR 285 - Project Area B","_id":"132"},{"_id":"142","name":"TRR 285 – B03: TRR 285 - Subproject B03"}],"_id":"30720","user_id":"14931","department":[{"_id":"630"}],"language":[{"iso":"eng"}],"year":"2021","citation":{"ama":"Hofmann M, Shi Y, Wallmersperger T.
