Computational homogenization of heterogeneous media under dynamic loading
Chenchen Liu, Celia Reina
A variational coarse-graining framework for heterogeneous media is developed that allows for a seamless transition from the traditional static scenario to a arbitrary loading condi…
Discrete averaging relations for micro to macro transition
Chenchen Liu, Celia Reina
The well-known Hill's averaging theorems for stresses and strains as well as the so-called Hill-Mandel principle of macrohomogeneity are essential ingredients for the coupling and…
Formation of Nanotwin Networks during High-Temperature Crystallization of Amorphous Germanium
Luis A. Sandoval, Celia Reina, Jaime Marian
Germanium is an extremely important material used for numerous functional applications in many fields of nanotechnology. In this paper, we study the crystallization of amorphous Ge…
Derivation of as the continuum limit of crystalline slip
Celia Reina, Anja Schlömerkemper, Sergio Conti
In this paper we provide a proof of the multiplicative kinematic description of crystal elastoplasticity in the setting of large deformations, i.e. $\mathbf{F}=\mathbf{F}^e\mathbf{…
Mesoscale computational study of the nano-crystallization of amorphous Ge via a self-consistent atomistic - phase field coupling
Celia Reina, Luis Sandoval, Jaime Marian
Germanium is the base element in many phase-change materials, i.e. systems that can undergo reversible transformations between their crystalline and amorphous phases. They are wide…
Kinematic description of crystal plasticity in the finite kinematic framework: a micromechanical understanding of F=FeFp
Celia Reina, Sergio Conti
The plastic component of the deformation gradient plays a central role in finite kinematic models of plasticity. However, its characterization has been the source of extended debat…
