Nanotwinned polycrystals exhibit an excellent strength-ductility combination due to nanoscale twins and grains.However,nanotwin-assisted grain coarsening under
stable high-order Runge-Kutta discontinuous Galerkin (RKDG) schemethat strictly preserves positivity of the solution is designed to solve the Bokzmann ki-netic eq
In this paper,the mechanical responses of a thick-walled functionally graded hollow cylinder subject to a uniform magnetic field and inner-pressurized loads are
