Internal Friction

internal friction

[in′tərn·əl ′frik·shən] (fluid mechanics) viscosity (mechanics) Conversion of mechanical strain energy to heat within a material subjected to fluctuating stress. In a powder, the friction that is developed by the particles sliding over each other; it is greater than the friction of the mass of solid that comprises the individual particles.

Friction, Internal

a group of various processes within solids, and in liquids and gases, that lead to the irreversible dissipation of mechanical energy during deformation through the transformation of mechanical energy into heat. (SeeINTERNAL FRICTIONIN SOLIDS; regarding internal friction in liquids and gases, seeVISCOSITY.)
