Abstract
The initial phase of feather joint development in the vicinity of a turnpike longitudinal shear vertex is analyzed. Experiments with model materials demonstrate that the crack parameters and the distance between the cracks along the shear front in the primary echelon brittle fracture structure linearly depend on the shear radius. A model for the development of the primary echelon structure along the longitudinal shear front is proposed.
