0]) denoting the slip direction and slip plane normal, respectively, at time t = 0, the constitutive equations relate the following basic fields (all quantities expressed in crystal lattice coordinate frame): the deformation gradient F defined with respect to the initial undeformed crystal which can be decomposed into elastic and plastic parts as F = [F.
The three indices enclosed in parentheses (hkl) and the three indices enclosed in square brackets [uvw] represent the slip direction and the plane Miller indices, respectively.
Once the critical resolved shear stress in the slip direction is exceeded, slip becomes translation along the plane (Fig.
alpha]] are a pair of orthogonal unit vectors defining the slip plane normal and the slip direction, respectively.
He also demonstrated that the slip direction may be parallel to the direction of maximum shear stress resolved along the preexisting fracture surface.
The slip direction for episode 2 brittle reactivation based on Angelier's method supports this assertion, showing nearly horizontal slip (Fig.
Like for orthorhombic polyethylene and PEEK (11, 13) eight slip systems are taken into consideration, either with the slip direction along the chain axis ("chain slip") or perpendicular to the chain axis ("transverse slip").
Elastic as well as plastic deformations initially occur along these slip directions.
