Generalized continuum theories such as couple stress theory and micropolar theory have degrees of freedom in addition to those of classical elasticity. Such theories are thought to be applicable to materials with a fibrous or granular structure. In this study we observe size effects in quasistatic b...

Zusammenfassung:Generalized continuum theories such as couple stress theory and micropolar theory have degrees of freedom in addition to those of classical elasticity. Such theories are thought to be applicable to materials with a fibrous or granular structure. In this study we observe size effects in quasistatic bending of compact bone. The effects are consistent with micropolar theory. From them we evaluate two nonclassical elastic constants.
