Abstract: | Features of evolution of wedge-shaped twins in bismuth single crystals with polysynthetic twins are examined. Polysynthetic
twins are found to promote an increase in number, and a decrease in length, of indentation-induced wedge-shaped twins. The
latter quantities depend on the density of twins in a polysynthetic twin. Based on the dislocation model, stress fields in
the vicinity of wedge-shaped and polysynthetic twins are calculated at a mesoscopic level.
