This chapter discusses multiscale modeling methods for the study of deformation and fracture in metallic materials. Both atomistic and dislocation dynamics modeling are outlined in the context of problems in materials failure. In particular, molecular statics and dynamics models are described as applied to polycrystalline samples of random grain orientations and grain sizes in the nanometer regime. The application of dislocation dynamical models to mesoscale dislocation dynamics is then presented. Finally, dislocation pattern formation at various length scales is discussed as an illustration of multiscale modeling. [ABSTRACT FROM AUTHOR] |
