%X In this paper, the orientation of grains which adjacent to a developed opening crack was investigated by EBSD. A definition of <em>¦È</em> has been came up with which represents the angle between the principal stress plane and each   plane of the grains. Smaller <em>¦È</em> means easier to crack. It gave a good explanation of the crack propagation throughout the grains. It also revealed that propagation path is along with the   plane. This finding will give a prediction of tear properties and help us understanding the cracking mechanism and the behavior of tearing.
