On Defects in Solids
The thermodynamical potential for dilute solutions is rederived, generalized and applied to defects in solids. It is shown that there are always defects in solids, i.e. there is no perfect solid at any finite temperature. Apart from the temperature-dependent concentration of defects, another case is presented, where the defect concentration does not depend on temperature. With standard notation...
متن کاملFracture Toughness of Cellular Solids using Finite Element Based Micromechanics
Micromechanical methods to predict the fracture behavior and estimate the fracture toughness of cellular solids and foams are presented in this paper. The microstructure of the foam is modeled using finite elements. The struts of foam are modeled using either structural elements such as beams or three-dimensional solid elements. A portion of the foam containing an edge crack is modeled. Displac...

متن کاملOn two micromechanics theories for determining micro±macro relations in heterogeneous solids
The average-®eld theory and the homogenization theory are brie ̄y reviewed and compared. These theories are often used to determine the eective moduli of heterogeneous materials from their microscopic structure in such a manner that boundary-value problems for the macroscopic response can be formulated. While these two theories are based on dierent modeling concepts, it is shown that they can ...
متن کاملLattice models in micromechanics
This review presents the potential that lattice ~or spring network! models hold for micromechanics applications. The models have their origin in the atomistic representations of matter on one hand, and in the truss-type systems in engineering on the other. The paper evolves by first giving a rather detailed presentation of one-dimensional and planar lattice models for classical continua. This i...
