Research topic 1:
The direct numerical modelling of the fracture behavior of cellular materials with periodic microstructure
is a heavy task even for the 2D case. However, employing the discrete Fourier transform allows to get an
efficient and nice solution. This was shown recently in the papers published in the framework of PhD dissertation of Fabian Lipperman (see List of Publications). The success of this work which was funded by the Israel Science Foundation
allowed to get a new grant (also from ISF) for the extending of the developed method to the practically more interesting 3D case. This is the main topic of the suggested study.
Research topic 2:
Outstanding fracture properties of the Nacre-Mother of Pearl stimulated intensive study of this phenomenon. Since the microstructure of this seashell material is periodic it is believed that employing the novel Representative Cell Method will lead to convenient models of crack propagation in this material. The parametric study will help to design new bio-inspired crack arresting materials.
