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

Your Profile

• M.Sc. student in Mechanical Engineering, Manufacturing Engineering, Computational Engineering, Materials Science, Mechatronics, Physics, or a related field
• Interest in simulation, material modeling, and advanced manufacturing technologies
• Experience with numerical methods such as FEM, multi-physics simulation, or computational modeling
• Familiarity with material behavior and structural mechanics
• Programming skills (Python preferred)
• Experience with simulation software is a plus
• Analytical mindset and enthusiasm for solving complex engineering problems
• Motivated, independent, and eager to learn
• Excited by the pace and responsibility of a startup environment

What We Offer

• A highly relevant industrial research topic
• Direct impact on innovative manufacturing technology
• Close collaboration with experts in laser processing and joining
• Startup culture with flat hierarchies and fast decision-making
• Flexible start date and room for your own ideas
