Modeling of trabecular bone transition into plastic deformation stage under uniaxial compression

This article deals with the nonlinear behavior of trabecular bone tissue under uniaxial compression. The model this is a stress-strain curve an ascending branch, peak point, and descending branch. known predicts at pre-peak partially post-peak stage deformation. does not take into account transition plastic deformation appearance residual deformations, which (depending on scale) may be physiologically unacceptable. aim work to predict point state. proposes implements approach based joint application differential energy criterion brittle fracture. study contributes development new models, use improves possibilities analyzing mechanical impact, important for practice load rationing in traumatology sports medicine. small amount initial data positive quality proposed modeling Given volume studies using approach, it necessary continue research direction, despite good agreement results experimental from literature.
