✦ Synopsis

To understand the inelastic response of bone, a three-part investigation has been conducted. In the first, unload/reload tests have been used to characterize the hysteresis and provide insight into the mechanisms causing the strain. The second part devises a model for the stress/strain response, based on understanding developed from the measurements. The model rationalizes the inelastic deformation in tension, as well as the permanent strain and hysteresis. In the third part, a constitutive law representative of the deformation is selected and used to illustrate the coupled buckling and bending of ligaments that arise when trabecular bone is loaded in compression.

## Abstract Limited __in vivo__ and __in vitro__ experiments suggest that bone and bone‐like cells respond to mechanical signals in a trigger‐like rather than a dose‐response fashion; i.e., they fail to respond until they have been stimulated with some given number of cycles of loading, and then on
