MODELING OF TRABECULAR BONE AS A COUPLE STRESS CONTINUUM

摘要

We model trabecular bone as an idealized periodic structure made of open cubic cells and represent it as a linear elastic couple stress continuum. We find couple stress moduli for such material using displacement and traction boundary conditions. Several different loadings are applied to obtain these couple stress constants: uniaxial extension (or tension), hydrostatic deformation (or pressure), applied curvature (or bending moment), and twist (or torsion).
