Laboratory for Material Texture

Microstructure Simulations

I. Monte Carlo Simulation

A new through-process mesoscopic model was presented for predicting grain boundary migration. The strain-induced grain growth was simulated on an aluminum bicrystal after 5% plane strain compression. The 2D full strain fields determined by using digital image correlation (DIC) technique provided data to predict grain growth using a modified Monte Carlo method. The simulation results of the strain-induced grain growth on grain boundary were compared with experimental results.

II. Taylor Model

Taylor model gives a well approximation of a deformed texture in polycrystalline materials. The {111} pole figure above shows the result of a random textured material after uniaxial tension along the rolling direction.
