Sample text

For the ith layer the relation between the (micro-)stress σ i and the (micro-)strains εi is given by the (micro)stiffness matrix Di and reads In order to establish the relationships between stresses and strains in a homogenized continuum, the following averaged quantities in an equivalent prism are defined: where V is the volume of the representative prism and j indicates all the components of the stress and strain tensors. Auxiliary stresses (t1 , t2 and t12 ) and auxiliary strains (e3 , e13 and e23 ) are introduced as a deviation measure of the ith layer stress/strain state from the averaged values.

However, for stratified soils and fractured rocks, a continuum assumption often leads to difficult parameters to define and over-simplified geometry to be realistic. In such cases, approaches that consider the micro-structure of the material can be adopted. In this paper, two of such approaches are detailed, namely limit analysis incorporating fractures and individual blocks, and elastoplastic homogenization of layered soils. 1 INTRODUCTION The present paper addresses the inelastic behavior of heterogeneous media, such as soils and rocks.
