A dynamic lattice model for heterogeneous materials
In this paper, the mechanical behavior of three-phase inhomogeneous materials is modeled using the meso-scale model with lattice beams for static and dynamic analyses. The Timoshenko beam theory is applied instead of the classical Euler-Bernoulli beam theory and the mechanical properties of lattice beam connection are derived based on the continuum medium using the non-local continuum theory. T...
متن کاملA 2D constitutive non-linear model with anisotropy for granular materials
Dense granular materials behave differently from classical fluids or solids and can not be described through the continuum theories developed for those. In fact behavior at macro-scale is strongly related to smaller-scale field variables and kinetic processes. The influence of the micromechanics on the non-coaxiality of stress, strain and anisotropy of soils, is an essential part of a constitut...
متن کاملLattice Models in Materials Science
This thesis presents the results of investigations on three independent research topics of modern biophysical and materials science research: substitutional diffusion in binary alloys, the remodelling process in trabecular bone and the prediction of mechanical properties of self assembling, amphiphilic bilayers. The basic description of all three projects is based on lattice models, a highly su...
متن کاملWeb - based Supplementary Materials for “ On selection of spatial linear models for lattice data ”
The following regularity conditions are made. (A.1) X has full rank p and η ∈ Ω where Ω is an open subset of R p+q+1 that contains η 0. (A.2) Γ γ is twice differentiable with respect to γ with continuous second-order derivatives and is positive definite.
متن کاملA Review of Constitutive Models for Rubber-Like Materials
Problem statement: This study reviewed the needs of different constitutive models for rubber like material undergone large elastic deformation. The constitutive models are widely used in Finite Element Analysis (FEA) packages for rubber components. Most of the starting point for modeling of various kinds of elastomer is a strain energy function. In order to define the hyperelastic material beha...
