The Relationship

Based on Hertz elastic contact theory, the contact mechanics model of two cosine wave is established. The mechanical characteristics of the model in the elastic, elastic-plastic, and plastic stages were studied. The influence of load on contact deformation and other characteristics is considered. The finite element method is used to analyze the deformation process of the model, and the results are compared with those of the mechanical model. The effects of amplitude and wavelength of cosine wave on its mechanical characteristics are discussed. The results show that the model reflects the relationship between the load and the mechanical characteristics of the model, and the difference of amplitude and wavelength will affect this characteristic.

A theoretical model is proposed to describe the mechanical behavior of mammalian tendon. The tendon is modeled as an incompressible fiber-reinforced composite with continuously distributed inextensible fibers. The fibers describe helices with constant pitch on concentric right circular cylinders. The analysis is, essentially, independent of the material behavior and, for example, applies to nonlinear elastic solids and viscoelastic materials. A boundary-value problem for tendon extension is discussed in detail and, for a particular nonlinear elastic solid, the deformation and stress are determined to be in qualitative agreement with existing experimental results.
