When polymers are exposed to mechanical stress, the structural and spectroscopic properties of the materials change, which can be used for the change in color of materials under stress or for self-healing. Many effects that emerge during mechanical deformation have not yet been understood: What are the factors that lead to material failure in a certain part of the polymer, while other parts stay intact? How can the color response be optimized to achieve a significant color change well before material failure occurs? How can self-healing processes be optimized? To answer these questions, computational methods for the description of molecules under mechanical stress are developed and applied.
