Derivation of Higher Order Gradient Continuum Models from Atomistic Models for Crystalline Solids
We propose a new upscaling scheme for the passage from atomistic to continuum mechanical models for crystalline solids. It is based on a Taylor expansion of the deformation function and allows us to capture the microscopic properties and the discreteness effects of the underlying atomistic system up to an arbitrary order. The resulting continuum mechanical model involves higher order terms and ...
متن کاملLocally Anisotropic Interactions: III. Higher Order Anisotropic Supergravity
A general approach to formulation of supergravity in higher order anisotropic superspaces (containing as particular cases different supersymmetric extensions and prolongations of Riemann, Finsler, Lagrange and Kaluza–Klein spaces) is given. We analyze three models of locally anisotropic supergravity.
متن کاملInequalities for Higher Order Ising Spins and for Continuum Fluids*
The recently derived Fortuin, Kasteleyn and Ginibre (FKG) inequalities for lattice gasses are investigated for higher order Ising spin systems and multi-component lattice gasses. Conditions are given for the validity of the FKG inequalities for higher order spin systems with Hamiltonians of the form used recently as models for various physical systems, e.g. He — He mixtures. We also investigate...
متن کاملA Gradient Enhancement with Application to Anisotropic Continuum Damage
Abstract.The paper focuses on the modelling of the quasi-brittle failure of materials with a heterogeneous microstructure. Failure induced anisotropy is incorporated in terms of the microplane theory. This theory is based on scalar damage laws formulated on several individual material planes. Anisotropy of the overall constitutive law is introduced in a natural fashion by transforming the scala...
متن کاملHigher Order Gradient Continuum Description of Atomistic Models for Crystalline Solids
We propose an upscaling scheme for the passage from atomistic to continuum mechanical models of crystalline solids. It is based on a Taylor expansion of the deformation function up to a given order and describes the material properties to a higher extent than commonly used continuum mechanical models. In particular, the discreteness effects of the underlying atomistic model are captured. The qu...
