Abstract
An elastic-plastic constitutive model is developed to describe the deformation behavior of aluminum single crystals. The elastic response of the material is calculated in the framework of anisotropic elasticity theory. The plastic behavior is represented by a crystal plasticity model based on Schmid's law. Following this approach, plastic strains are derived in terms of the dislocation glide along the active slip systems involved. A slip system is assumed to be activated providing that the resolved shear stress takes on a critical value there. Finite-element calculations for uniaxial compression of single crystals with different crystallographic orientations are performed. The crystallographic orientation effect on the plastic strain localization is investigated.
