Abstract Scope |
Decomposing the total deformation gradient into elastic, eigenstrain, and
plastic components opens the door to concurrently couple various mechanisms
and associated transport phenomena to the standard crystal plasticity solution
of mechanical equilibrium. The talk highlights recent advances in implementing
staggered solution schemes for heat and mass transport as well as phase
field damage that allows concurrent coupling to the solution of mechanical
equilibrium for arbitrary elastic, eigenstrain, and plastic material
behavior with DAMASK. Examples to demonstrate these capabilities include the
variation of the internal stress field during thermal cycling of polycrystalline
hexagonal Ti and the stress-driven mass redistribution in plastically
relaxing Sn films under thermal stress. |
