The mechanical properties of olivine-rich rocks are key to determining the mechanical
coupling between Earth's lithosphere and asthenosphere. In crystalline materials, the motion …

Mantle flow involves large strains of polymineral aggregates. The strongly anisotropic plastic
response of each individual grain in the aggregate results from the interactions between …

In the present paper, a rational report on Euromech 563, Generalized continua and their
applications to the design of composites and metamaterials (Cisterna di Latina 17–21 March …

Grain boundaries play an important role in the mechanical and physical properties of
polycrystalline metals. While continuum macroscale simulations are appropriate for …

The microstructure evolution due to thermomechanical treatment of metals can largely be
described by viscoplastic deformation, nucleation and grain growth. These processes take …

Strain aging phenomena are shown to affect the viscoplastic behavior of commercially pure
α-titanium at room temperature. A yield stress anomaly corresponding to static strain aging …

The dislocation density tensor computed as the curl of plastic distortion is regarded as a new
constitutive variable in crystal plasticity. The dependence of the free energy function on the …

The shear-coupled boundary migration of< 0 0 1> symmetric tilt boundaries is investigated
within the framework of an elasto-plastic theory of disclination and dislocation fields. The tilt …

Because of the enormous range of time and space scales involved in dislocation dynamics,
plastic modeling at macroscale requires a continuous formulation. In this paper, we present …

Abstract The Continuum Dislocation Dynamics (CDD) theory and the Discrete Dislocation
Dynamics (DDD) method are compared based on concise mathematical formulations of the …
