Master Thesis at a Deep Tech Startup (HYJOIN)

Simulation Framework for HybridMetal-Plastic Joints Based on MicroscaleMechanical Interlocking

Join HYJOIN and develop the next generation of predictive engineering tools for intelligent joining technology. In this thesis, you will develop a simulation framework to model and predict the performance of hybrid metal-plastic joints created through laser-structured surface technologies and thermal direct joining. By combining different modeling approaches and data-driven evaluation, you will create methods to evaluate joint stiffness, strength, durability, sealing performance, and environmental robustness.

Your Tasks

Develop a simulation framework for hybrid metal-plastic joining technologies
Model mechanical interlocking between laser-structured metal surfaces and polymers
Validate and implement numerical approaches to predict joint strength, thermal behavior and failure behavior of thermally direct joined components
Analyze the influence of surface structure geometry on mechanical performance
Evaluate the effects of temperature, humidity, and environmental influences on joint properties
Correlate simulation results with experimental manufacturing and testing data
Develop software tools and workflows for automated simulation and design evaluation
Validate and optimize the models using real industrial applications
