Abstract
We study pattern selection of cracks in directionally drying fractures by analyzing the experimental systems recently devised by C. Allain a nd L. Limat [Phys. Rev. Lett. 74 (1995) 2981]. Proposing a simple pict ure of crack formation, we clarify the mechanism of how cracks become regularly arrayed and find that the interval between neighboring crack s is proportional to the 2/3 power of the cell thickness. This result explains well the experimental data of Allain and Limat.
