摘要
Texture is referred to as the crystallographic lattice preferred orientation (CPO) produced in polycrystalline rock by plastic deformation. Based on the crystal plasticity theory, numerical modeling is efficient and powerful in calculating the formation and evolution of texture in polycrystalline rocks. Plastic deformation is therein accomplished by an infinite number of slips occurring in the slip systems of each individual crystal. Numerical modeling of textures has been applied to geosciences for decades, in the development of monophase and polyphase rock textures and of textures formed due to dynamic recrystallization.
