Computational modelling and experimental characterisation of heterogeneous materials [PDF]
, 2009 Heterogeneous materials can exhibit behaviour under load that cannot be described by classical continuum elasticity. Beams in bending can show a relative stiffening as the beam depth tends to zero, a size effect.

A higher order control volume based finite element method to prodict the deformation of heterogeneous materials [PDF]
, 2013 Materials with obvious internal structure can exhibit behaviour, under loading, that cannot be described by classical elasticity. It is therefore important to develop computational tools incorporating appropriate constitutive theories that can capture ...

A control volume-based finite element method for plane micropolar elasticity [PDF]
, 2008 This paper describes the development of a numerical procedure for predicting deformations and stresses in a loaded two-dimensional membrane exhibiting micropolar or Cosserat constitutive behaviour. The procedure employs a conventional finite element (FE)

Haversian canal structures can be associated with size effects in cortical bone [PDF]
, 2012 Prediction of periprosthetic failure may be improved by an improved model of bone elasticity which includes microstructural information. Micropolar theory facilitates such information to be included in a continuum model.

The influence of void size on the micropolar constitutive properties of model heterogeneous materials [PDF]
, 2013 In this paper the mechanical behaviour of model heterogeneous materials consisting of regular periodic arrays of circular voids within a polymeric matrix is investigated.

, 2023 There are materials with internal structure (e.g. composites, polymers, liquid crystals, soil, and bone) for which a reasonable model should view the points no longer as purely geometric in character but as rigid-body particles or even deformable ...

MHD OBLIQUE STAGNATION-POINT FLOW OF A MICROPOLAR FLUID [PDF]
, 2011 The steady two-dimensional oblique stagnation-point flow of an electrically conducting micropolar fluid in the presence of a uniform external electromagnetic field (E0,H0) is analyzed and some physical situations are examined.

MHD THREE-DIMENSIONAL STAGNATION-POINT FLOW OF A MICROPOLAR FLUID [PDF]
, 2011 The steady three-dimensional stagnation-point flow of an electrically conducting micropolar fluid in the absence and in the presence of a uniform external electromagnetic field (E0,H0) is analyzed and some physical situations are examined. In particular,

Size effects in cellular solids [PDF]
, 2007 The mechanical properties of metal foams (and other cellular solids) depend on the properties of the metal that they are made from, on their relative density, and on the cell topology (i.e., cell size, cell shape, open or closed cell morphology, etc ...
