| Popis: | Technische Mechanik; 35; 1; 62-70; ISSN 2199-9244 In this article, the slip mechanisms card deck glide and pencil glide are recaptured. These mechanisms are useful simplifications when several slip systems in crystals, bundle- or plate-like structurs share a common shear plane n or a common shear direction d. It is pointed out that a third glide mechanism for slip systems with a common plane of shear k = d ՠn exists. For this second pencil glide mechanism, its properties are examined, a flow rule is derived, and the push-forward of k in case of large elastic strains is discussed. It turns out that the second pencil glide mechanism leads to a plane strain Prandtl-Reuss-like flow rule. Thus, unlike the pencil and the card glide mechanism, there is no accompanying lattice spin. |
