| | Summary: |
| | The cases that occur in the implementation of the smooth reinforcement steel bars are
analyzed. Geometry of the initial cracks on axially tensioned cylindrical rods are taken from
calculations basedon the rheological-dynamical analogy (RDA). Plastic zone size is determined
by Dugdale model. From the fracture mechanics standpoint, model is reduced to a plane with
symmetrically placed edge cracks. |
