The research project intends to develop a simulation-supported method for analyzing the strength and failure of sealed seams. A parameterizable model is set up, which can be used to make predictions regarding the failure behavior of sealed or welded seams. With the help of the simulation model it is possible to analyze geometric and material properties influencing factors on the seal seam strength. The simulation model enables investigations into:

  1. Influence of the film composite structure, e.g. substitution of carrier layers or barrier layers,
  2. Influence of the sealing technology/tool, and
  3. Influence of the technology-specific process parameters on the formation of the sealed seam and
  4. Influence of the seal seam formation on the seam strength.

The result is a calculation tool that can show the relationships between influencing factors and seam strength based on the materials examined in the project.
