The elastic moduli of human subchondral, trabecular, and cortical bone tissue from a
proximal tibia were experimentally determined using three-point bending tests on a …

A microstructure-dependent nonlinear Euler–Bernoulli and Timoshenko beam theories
which account for through-thickness power-law variation of a two-constituent material are …

Microcontinuum field theories constitute an extension of classical field theories--of elastic
bodies, deformations, electromagnetism, and the like--to microscopic spaces and short time …

This study presents analysis on the vibration behavior of the two-dimensional functionally
graded (2D-FG) nano and microbeams which are made of two kinds of porous materials for …

A microstructure-dependent Timoshenko beam model is developed using a variational
formulation. It is based on a modified couple stress theory and Hamilton's principle. The new …

A new model for the bending of a Bernoulli–Euler beam is developed using a modified
couple stress theory. A variational formulation based on the principle of minimum total …

The classical and shear deformation beam and plate theories are reformulated using the
nonlocal differential constitutive relations of Eringen and the von Kármán nonlinear strains …

This work examines the effect of microstructure upon microcantilever bending stiffness. An
existing beam theory model, based upon an isotropic Hooke's law constitutive relationship …

Auxetic materials expand when stretched, and shrink when compressed. This is the result of
a negative Poisson's ratio ν. Isotropic configurations with ν≈− 1 have been designed and …

Experiments are performed to determine the dependence of torsional and bending rigidity
upon diameter for rod-shaped specimens of dense polyurethane foam and syntactic foam …
