Analysis of anisotropy in sheet forming using polycrystal plasticity

Polycrystal plasticity theory has provided a useful tool for detailing the development of crystallographic texture in deformation processes. The theory has been applied by many researchers, both free-standing and in concert with finite element procedures, to analyze microstructural evolution. Studies have been carried out to predict microstructural response in idealized deformations, industrial processes such as rolling and sheet forming, and geologic motions. Recent advances in computational hardware, specifically massive parallel processing architectures and the software algorithms necessary to exploit these advances, have enabled the modeling of more complex processes such as sheet forming operations. In this work simulations of sheet forming will highlight the scalability of the code as well as the effect of anisotropy on formability.
