Attachment of dissimilar materials can result in high levels of localized stress at their interfaces, which can predispose a structure to failure. The stress concentrations at such interfaces are well characterized for linear elasticity. However, extending this understanding to nonlinear materials is not straightforward. In biological materials, local stiffness may increase in response to elevated stress, and in metals, local stiffness may decrease; however, the effect of this is not well characterized for free edge singularities. The main goal of this research was therefore to investigate the effect of nonlinearity using numerical analysis, then to describe stress concentrations that arise at tendon-to-bone interfaces, and to assess how these concentrations change when one of the materials (here, tendon) stiffens with straining.
