Transfer performance of the LWF for crash simulation

Following the publicly funded research project " Method development for damage modeling in the numerical simulation of mechanical joining processes (AiF-No.: 19452 N)", which was successfully completed at the Laboratory of Materials and Joining Technology (LWF), an industrial implementation of the results was realized. In the latest version of the simulation software Simufact. Forming 2021, for the first time an assistant for damage modeling was provided. According to the software developer, the user benefits from the newly generated damage model, which enables accurate calculations in the future. [1]. To calibrate the parameters of the damage model, the findings of the research project have been used. In this research project, a method was developed to predict the evolution of the ductile damage and material separation in the simulation of mechanical joining processes. By accurate prediction of the pre-damage and material separation in the simulation of joining process, the accuracy of crashworthiness simulations can be improved. Besides, over dimensioning will be reduced and more precise components will be designed.

The IGF research project (IGF-Project 19452 N) "Method development for damage modeling in the numerical simulation of mechanical joining processes" of the European Research Association for Sheet Metal Working (EFB) was funded by the German Federation of Industrial Research Associations (AiF) under its program for the promotion of industrial research (IGF) by the Federal Ministry for Economic Affairs and Energy (BMWi) based on a decision of the German Bundestag. We would like to take this opportunity to thank the Research Association for its financial support and organizational supervision. Further thanks go to all cooperating industrial partners for the good support and cooperation within the scope of the project.
