UNITED PROOF FOR QUALITATIVE PROPERTIES OF DISCRETE AND CONTINUOUS SYSTEMS OF VIBRATING ROD AND BEAM
-
Abstract: Applying a method of limit transition, we have come to the oscillatory properties of Green's functions of continuous systems from the sign oscillatory properties of stiffness matrices of discrete systems for a vibrating rod or beam.
