| Research Abstract |
Validity of the phase-field model that is introduced by the author and Dr. Kimura is estimated both theoretically and numerically. Relation between the spatial profile of the equilibrium state of phase-field and the regularization parameter is studied theoretically. It is also shown numerically that the basement value of the damage (or the micro-crack density) controls the number of crack lines. 3-dimensional crack propagation is studied numerically, and the twist of crack surface is investigated. The stereo-viewer for 3-dimensional numerical data of FreeFem++ is developed, and the numerical code development for the large scale crack propagation is now in progress.
