000015203 520__ $$2eng$$aWe investigated how coherent interfaces, between f.c.c./h.c.p. systems, affect large strain deformation and fracture modes in h.c.p. zircaloy aggregates with f.c.c. hydrides. We derived 36 unique transformations related to coherent interfaces between f.c.c. and h.c.p. systems. We then used these ORs with a dislocation-density crystalline plasticity formulation, a non-linear finite-element and a fracture approach that account for crack nucleation and propagation. We investigated how these ORs affect crack nucleation and propagation, dislocation density and inelastic slip evolution, stress accumulation, lattice rotation, and adiabatic heating. The predictions indicate that the physical representation of ORs affect local deformation and fracture behavior, and are, therefore, essential for accurate predictions of behavior at different physical scales in heterogeneous crystalline systems.
