- Abstract
- This work combined experiments at the grain level with the constitutive modeling of a single crystal to investigate deformation behaviors of a pure aluminum single crystal oriented for a single slip. Simple compression of a [<(1) over bar>132] single crystal was conducted to obtain the macroscopic stress-strain response and observe the deformed shape of the sample. The evolution of the crystallographic orientation was measured by an electron backscattered diffraction system in a field emission scanning electron microscope. The heterogeneous in-plane surface deformation in a single crystal was calculated by using a digital image correlation technique. Finite element modeling based on a single crystal plasticity model agrees well with experimental results in an averaged sense, not at the individual dislocation level.
