Dynamic Analysis of Systems of Bars Encased in Elastic Medium,
Abstract
A general method is presented for the analysis of space frames encased fully or partially in elastic medium and subjected to time-dependent loads of harmonic variation, such as those arising from rotating or reciprocating machinery. Off-shore structures, pipelines, bridges, components of ships and aerospace structures are examples of such systems. The analysis is restricted to systems of straight linearly elastic bars of constant sections, which have two orthogonal axes of symmetry or are axial symmetrical. The time-independent mass of each bar is uniformly distributed along its axis. The material constants of each bar and of its surrounding medium are independent of time and are known from experiments. The sign convention of the transport method and of the stiffness method is used in the respective sections.
