| Research Abstract |
In this research, we studied several crack propagation models in fracture mechanics and related various moving boundary problems from viewpoints of mathematical and numerical analyses. These are completely different phenomena, however, both have geometrical difficulty and importance of variational structures. We succeeded in proposing a phase field model by means of reaction diffusion system, which is a powerful tool in moving boundary problems, and constructed a polygonal motion with variational structure and its numerical analysis.
