Extensions of the FE-tool for the simulation of the bond strength at the joining interface of aluminium alloys during mulit-pass hot roll bonding

Composite metals are increasingly valued for their tailored mechanical, chemical, thermal, and corrosion-resistant properties. Roll bonding is widely used in industry due to its efficiency and low cost, but process design often relies on experience, leading to long development phases. Recent advancements include a semi-empirical composite model for AA6xxx/AA8xxx developed by Dr. Alexander Krämer, which relates bond strength to various factors. This work focuses on enhancing the FE framework and developing a coupled mechanical-thermal model for process simulation.
