Abstract: A new compression-twist type friction testing machine has been developed to simulate the frictional conditions prevailing in metal forming. Twin indenter tools with different sliding length were ...

Abstract: To examine the seizure mechanism in cold extrusion and forging, a bifurcating extrusion type friction testing machine has been manufactured by the authors. This friction testing method was devised ...

Abstract: An experiment of ironing of aluminum cups has been carried out under various lubrication conditions. The surface appearances of the ironed cups can be classified into five main groups according ...

Abstract: A new testing apparatus has been made to analyze the ironing of thin metal cups. The frictional force Fp that acts axially along the punch side could be measured independently of the punch ...

Abstract: This paper reviews the new concept “microfactory” and related developments. Machined parts are becoming progressively smaller, so production machinery that remains a conventional size is often ...

Abstract: Deterioration of aging bridges is a serious problem that affects their serviceability and durability. Appropriate repair, strengthening, or replacement work should be performed on aged bridge structures to ensure they ...

Abstract: Bridge accessories, such as parapets, service ducts, and track slabs, are commonly used in railway bridges, but their real effects on the structural behavior of the bridges are still unknown because very few studies have ...

Abstract: Preventive maintenance on aged steel railway structures is all important due to their long service time after completion. This paper introduced a strengthening method for old steel railway bridges by using rubber-latex ...

Abstract: Abstract. In electroencephalography (EEG) with dry electrodes, a tradeoff between signal stability and user comfort is a critical barrier to long-term, wearable applications. While various approaches exist, the mechanical ...
