Thermal Resistance of Contacts
Review of Scientific Instruments, 1973In order to obtain accurate thermal resistance data for contacts under high loads (i.e., P/M > 2×10−3) it is not always necessary to employ a high vacuum for transverse thermal insulation, or a guard-heater arrangement.

Thermal resistance of silicon point contacts
Physical Review B, 1989We investigate thermal transport on microcontacts established between two silicon wedges. The measurements are carried out with a variable contact radius of 0.3--2 \ensuremath{\mu}m at temperatures from 2 to 300 K. The measured thermal resistance is used to calculate the contact radius with an accuracy better than 50%.

A Device for the Skin–Contact Thermal Resistance Measurement
IEEE Transactions on Instrumentation and Measurement, 2012The skin-contact thermal resistance is a parameter that allows evaluating, in steady condition, the heat flow at the interface between the skin and a rigid surface at a known temperature. At the current state of the art, it is evaluated with empirical equations and is known to be dependent on the contact pressure, on the surface characteristics, and on

Introduction to Thermal Contact Resistance
2023Contact resistance has been an area of interest in engineering applications dating as far back as 1930. Yovanovich (2005) provides a comprehensive historical overview of the field with emphasis on the research-intensive period spanning the early 1960s to early 2000s.

Thermal resistance of metallic contacts
International Journal of Heat and Mass Transfer, 1964Abstract A calculation method for thermal resistance of a contact between two rough metal surfaces with different compressing forces and quality of finishing is considered. The results of analytical calculation are correlated with experimental data.

Thermal resistances of pressed contacts
Applied Energy, 1986Abstract Contacts between two surfaces under mechanical load occur frequently in numerous structures, yet their behaviour when heat is transferred across them is usually not fully appreciated. The present review is aimed at assisting the designer in understanding the intricacy of this problem and the factors involved.

Advances in thermal contact resistance studies
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2022The demand for accurate Thermal Contact Resistance analysis and prediction continues to increase with the advancement of technology. In applications such as manufacturing, it is beneficial to understand the Thermal Contact resistance between the workpiece and tool, or between the tool and debris or shavings to accurately predict the tool wear rate.

CAE/CAD and Thermal Management Issues in Electronic Systems, 1997
Abstract The thermal contact resistance at the interface of a bolted joint was investigated analytically, experimentally and numerically. Consideration was restricted to an ideal two-plate model for which the interface was perfectly flat. The two bolted plates made circular contact under uniform axisymmetric normal loading. The effect of

Influence of thermal contact resistance on thermal impedance of microelectronic structures
Microelectronics Reliability, 2007Abstract The thermal impedance Z th (j ω ) has been calculated numerically for a silicon chip glued on a ceramic substrate. The non perfect thermal contact is taken into account by modelling the chip-substrate interface as a thermal contact resistance r c . If Z th is represented as a Nyquist plot, mainly two circular arcs are observed.
