“…Similar to KE, Song et al [72,73] studied the effect of size-dependent plasticity on the contact behavior of rough surfaces. Zhang et al [74] analyzed the deformation process of rough surfaces by using the strain gradient plasticity constitutive theory (CMSGP for short) by using a finite element method. They developed a full-scale elastoplastic contact model at different size levels.…”

Contact and friction are closely related as friction cannot happen without contact. They are widely used in mechanical engineering, traffic, and other fields. The real contact surface is not completely smooth, but it is made up of a series of tiny contact asperities as viewed in the micro-scale. This is just the complexity of the contact and friction behaviors of rough surfaces: the overall mechanical behavior is the result of all asperities which are involved during the contact. Due to the multiplicity of surface topography, the complexity of contact scale, and the nonlinearity of the constitutive material, there are still many open topics in the research of contact and friction behavior of rough surfaces. Based on the perspective of the macroscopic and micro-nano scale contact mechanics, this review gives a brief overview of friction for the latest developments and points out the existing issues and opportunities for future studies.

“…In many studies, FEM simulations offer an alternative and convenient method to investigate rough surface contact considering complex influencing factors [21], for example the nonlinearity of materials. Song [22], Zhang [23], and Jiang [24] studied the contact behaviors of rough surfaces by taking size dependence into account. Zhang and Yang [25] noted that the indentation behaviors of hyperelastic spheres primarily depend on the combined influences of substantial deformation and material nonlinearity.…”

The intricacies of rough surface contact are amplified by hyperelastic materials, primarily due to nonlinear enhancement caused by stress concentration. In previous studies, we proposed an incremental contact model for hyperelastic materials based on the tangent modulus and validated it through finite element simulations. This study proceeds with the experimental validation of the model. Initially, four hyperelastic rough surfaces were scanned and stitched together using a white light interferometer to obtain the whole surface topography. Subsequently, in situ optical interferometric techniques precisely measured the actual contact areas between these four samples and quartz glass, establishing the relationship between the load and contact area. Finally, by incorporating the surface topography into the incremental contact model for hyperelastic materials using profile theory, predictions of the relationship between load and contact area were made and compared with the experimental results. Significant agreement was found within nearly 90% of the relative contact area, which validated the model’s efficacy. The importance of this model extends to practical domains, such as wear, sealing, and contact surface safety research.

The hyperelastic materials would contribute to the intricacies of rough surface contact, primarily due to the heightened nonlinearity caused by stress concentration. In our previous research, an incremental contact model tailored for hyperelastic materials is proposed and validated by finite element (FEM) simulations. From an experimental perspective, this study employs an in-situ optical interferometric technique to precisely document the actual contact zone between hyperelastic solids and quartz glass. Simultaneously, the contact force is meticulously recorded in sync by a force sensor positioned beneath the hyperelastic samples. Comparing with the predictions of incremental contact model for hyperelastic materials, a significant agreement becomes evident, almost in a range of nearly complete contact. Its significance extends to practical domains such as sealing mechanisms, leakage prevention, and structural integrity, offering valuable insights for these applications.
