In (a), we show the boundary condition: a polycrystal copper (FCC) with 2 × 2 × 2 mesh/grains under a tensile loading along the z-axis. The tensile experiment fixes the bottom surface and a corner and pulls the top surface with a prescribed displacement condition. b The simulation result of the z-z component of stress σzz extracted from the corner mesh/cell labeled “1” versus applied strain, obtained from JAX-CPFEM. Three Euler angles \(\left[{\alpha }_{i},\,{\beta }_{i},{\gamma }_{i}\right]\) applied to each mesh/grain are \([30^{\circ} ,\,40^{\circ} ,\,50^{\circ} ]\). The color contour bar in the figure represents the value of Euler angle.
