Linear analysis of a rod under dynamic loading

This example verifies the linear dynamic procedures in Abaqus by comparing the solutions with exact solutions for a simple system with three degrees of freedom.

Abaqus offers four dynamic analysis procedures for linear problems based on extraction of the eigenmodes of the system: modal dynamic analysis, which provides time history response; response spectrum analysis, in which peak response values are computed for a given response spectrum; steady-state dynamic analysis, which gives the response amplitude and phase when the system is excited continuously with a sinusoidal loading; and random response analysis, which provides statistical measures of a structure's response to nondeterministic loading.
