Mixed-mode cohesive cracks and complex potentials of linear elastic fracture mechanics: new theoretical aspects and numerical applications
(kassel university press, 2023)
The J-integral is a powerful tool to determine crack tip loading, where the J-integral vector also allows for the quantification of crack deflection applying the J-integral vector criterion. Although originally formulated for sharp cracks with a crack tip singularity, the J-integral vector can also be derived for cracks with cohesive zones. The relation and proof of equivalency of the first coordinate of the vector and the crack tip opening displacement, typically associated with the cohesive zone model, has been ...

Quantum Technology using Cold Diatomic Molecular Ions: Interferometry and Cooling
(kassel university press, 2023)
Atoms and atomic ions have proved to be useful as quantum technological systems, where atomic clocks are one of the more famous implementations. Molecules, with more degrees of freedom (vibrations and rotations) are considered as natural extensions to atomic systems. In particular, we study cold molecular diatomic ions as systems for implementation in quantum technology and in particular the rotational degree of freedom of such molecular ions. Quantum effects manifest themselves at very cold temperatures. To reach ...
