Summary:Title screen
The authors analyze folding in concavity areas. Special aspects of folding are determined both for natural concavities stipulated by specifics of crystallographic orientation and for deliberately created concavities inside a Ushaped cut. It is shown that at the macrolevel folding is caused by concavity areas, in other words the stress condition pattern has primary influence on initiation of folds. Development of folding structures is followed by misorientation of local areas inside the crystal. The misorientation leads to an increase in the Schmidt factor and initiating additional slide patterns inside the crystal at the mesolevel. Development and accumulation of misorientations at the microlevel correlate with those in the dislocation structure. A U-shaped incision helps to activate a larger number of slip systems and the emergence of additional deformation domains.
