Guidelines to use input contact parameters for nonlinear dynamic analysis of jointed structures: Results of a round robin test

Experimental dataset from a round robin test of contact parameters and hysteresis loops for nonlinear dynamic analysis

“…Data from this round robin provides hence a unique comparison of measurements, taken from two different rigs on specimens manufactured from the same batch of stainless steel. The factors that may cause differences in the measurements from the different test rigs have been instead discussed in detail in the related research article [1] . This data will particularly benefit researchers in the fields of joint mechanics, nonlinear dynamics, tribology and contact mechanics, who need to quantify contact parameters for their applications.…”

“…These values have been obtained with the MATLAB Ⓡ script “get_steadystate_values.m” and are needed to run statistical analyses on the uncertainty of the measured contact parameters. These files are the most important and have been used to show all the trends in the friction coefficient and tangential contact stiffness in the original research article [1] . It is possible to study and plot these data with the two MATLAB Ⓡ scripts “plot_SUMMARY_boxplot_figs.m” and “plot_SUMMARY_boxplot_figs.m”, as better described at the end of this section.…”

“…Although several fretting rigs have been developed at different institutions to measure contact parameters such as friction coefficient and contact stiffness, a lack of direct comparisons prevents a throughout understanding. To address this issue, a comparison of these contact parameters has been performed in [1] by employing the fretting rigs of Imperial College London and Politecnico di Torino. This data article adds value to the original research article [1] by making the raw and processed data publicly available [2] and reusable for further research and development.…”
