The mechanical properties can, to date, probably be regarded as the most important among all material properties. The tailoring of mechanical properties is, therefore, a key aspect of this book. As the vast majority of structural materials is of crystalline nature, modeling of crystal elastoplasticity became a key topic. This chapter, therefore, gives an introduction to the capabilities of crystal plasticity modeling. After a general introduction, the structure of crystal plasticity‐based constitutive models is introduced. The application part focuses on examples from the field of microstructural design. To not only use the initial texture to model anisotropic material behavior, but also predict texture evolution during forming is key strength of crystal plasticity modeling. It can, therefore, also be used for the optimization of textures and their evolution. The second block of examples illustrates the potential of crystal plasticity as a tool for full‐field homogenization and its use as the so‐called Virtual Laboratory.
