Various aspects of the structural theory of liquids
Abstract
Liquids are defined as belonging to a new class of structures, namely zero internal momentum mode structures as distinguished from statically determinate and indeterminate structures. From the structural point of view, zero momentum modes are fundamental to liquids. Constraint equations from the zero momentum condition result in irrotational modes of displacement for both statics and dynamics. Steady flow of incompressible liquids is treated as the initial structural response due to impulsive loads, small displacements.
