Friction during contact between metals can be very complex under dynamic conditions. In this study, friction 304 stainless steel and SKD11 with boundary lubrication was studied experimentally using a testing machine (MPX-2000). The coefficients at different sliding speeds interface loads were determined, new coefficient model established based on the experimental data. sample surfaces analyzed ...

Today, “Sustainable production” has attracted a great deal of interest by academic researchers and practitioners due to the raising environmental and social concerns. Sustainable EPQ model has been developed as a result of this interest and also necessity. This paper develops a novel sustainable EPQ (SEPQ) model under partial backordering consideration. The model converts all emission variation...
