Disc coal samples with different water content were tested using the split Hopkinson press bar test system. Their dynamic tensile failure process was monitored via an ultra-high-speed digital image ...
The rubber static friction coefficient μ s contributes, e.g., to the grip of tyres, shoes and windshield wipers, even though research is often focused on the sliding (dynamic) friction coefficient μ d ...
The functional lifetime of a wet clutch can be characterized using wear characteristics such as velocity dependence of the coefficient of friction (COF) and friction curves. Current market trends ...
