Limiting shear stress
NettetIn the analysis of rolling-sliding concentrated contacts, such as gears, bearings and traction drives, the traction characteristics of the lubricant are of prime importance. The elastic shear modulus and limiting shear stress properties of the lubricant dictate the traction/slip characteristics and power foss associated with an EHD contact undergoing … Nettet11. okt. 2024 · where. τ L0 is the limiting shear stress extrapolated to atmospheric pressure. Note that this parameter has no physical meaning since there is no valid reason why the LSS could happen in this condition. \({{\varLambda }}\) is a dimensionless parameter, specific to the considered lubricant and which may depend on temperature. …
