“…A numerical scheme known as the Sami-analytical method (SAM) has been developed in last decades, in which the ICs are derived analytically in frequency space and deformations are calculated by the FFT technique. Recent progresses along this approach include acquirement of expressions of the ICs for multilayer materials in contacts and extension of the SAM model to the analysis of thermoelastic contacts of inhomogeneous materials [630,631]. The newly appeared FFT-based boundary value method [632] is similar to that of SAM, but a new way of computing the coefficients of the conjugate gradient solver has been presented, which reduces the number of FFTs at each step.…”

“…To take account of more complex material responses and incorporate thermal, electric or magnetic effects is an important target in applications of contact mechanics. For example, the temperature distributions due to frictional heating in thermoelastic contacts have been solved through semi-analytical approach, with consideration of material inhomogeneity [630,631,642]. The analysis of thermoelastic contact has been further extended to evaluate the contact performance for the magneto-electro-elastic materials (MEEMs) [643].…”

The reach of tribology has expanded in diverse fields and tribology related research activities have seen immense growth during the last decade. This review takes stock of the recent advances in research pertaining to different aspects of tribology within the last 2 to 3 years. Different aspects of tribology that have been reviewed including lubrication, wear and surface engineering, biotribology, high temperature tribology, and computational tribology. This review attempts to highlight recent research and also presents future outlook pertaining to these aspects. It may however be noted that there are limitations of this review. One of the most important of these is that tribology being a highly multidisciplinary field, the research results are widely spread across various disciplines and there can be omissions because of this. Secondly, the topics dealt with in the field of tribology include only some of the salient topics (such as lubrication, wear, surface engineering, biotribology, high temperature tribology, and computational tribology) but there are many more aspects of tribology that have not been covered in this review. Despite these limitations it is hoped that such a review will bring the most recent salient research in focus and will be beneficial for the growing community of tribology researchers.

“…For example, Zhang et al established a semi-analytical model of the dynamic contact between a rigid ball and MEE film, and they analyzed the effect of the loading speed, film thickness and ball radius on the dynamic magneto-electro-elastic response [ 18 ]. Zhang et al proposed a contact model of a functionally graded, coated MEE medium and studied the effects of the coating thickness and coating parameters on the elastic, electric and magnetic fields of the coated medium [ 19 ]. Some have also paid attention to the effects of the electromagnetic field on the contact response.…”

The magneto-electro-elastic (MEE) medium is a typical intelligent material with promising application prospects in sensors and transducers, whose thermal contact response is responsible for their sensitivity and stability. An effective thermal contact model between a moving sphere and a coated MEE medium with transverse isotropy is established via a semi-analytical method (SAM) to explore its thermal contact response. First, a group of frequency response functions for the magneto-electro-thermo-elastic field of a coated medium are derived, assuming that the coating is perfectly bonded to the substrate. Then, with the aid of the discrete convolution–fast Fourier transform algorithm and conjugate gradient method, the contact pressure and heat flux can be determined. Subsequently, the induced elastic, thermal, electric and magnetic fields in the coating and substrate can be obtained via influence coefficients relating the induced field and external loads. With the proposed method, parametric studies on the influence of the sliding velocity and coating property are conducted to investigate the thermal contact behavior and resulting field responses of the MEE material. The sliding velocity and thermal properties of the coating have a significant effect on the thermal contact response of the MEE material; the coupled multi-field response can be controlled by changing the coating thickness between ~0.1 a0 and a0.

“…The results showed that the characteristic time varies exponentially with the moving speed, and the temperature field is very sensitive to the thickness of the discs. Zhang 28 applied a fast semi-analytical method to solve the three-dimensional thermoelastic contact problem. Although his model was verified against other solutions available in the literature and showed a high robustness and efficiency, there was no direct temperature measurement.…”

The temperature field of the wet clutch is an important factor that influences the vehicle transmission performance. In order to predict and prolong the service life of the wet clutch, a test bench is built, and an accelerated life test is carried out based on the actual working conditions. Then, according to the variation of the friction coefficient and the maximum radial temperature difference, the sliding temperature field is analyzed in different periods. By introducing four evaluation indexes, a temperature field evaluation system is established and verified. With the help of this evaluation system, the temperature fields during running-in and unstable stages are compared, and the thermal failure mechanism of the friction disc is analyzed. In the stable stage, the influence of rotational speed, oil pressure and lubricant flow on the temperature field are investigated. The results of this study can guide the design and control of the friction components in the wet clutch.
