内容简介：
Some interesting results on the dynamics of continuous systems are reviewed. They involve: 1) dynamic stability of translating media with time-varying lengths and/or velocities; 2) nonlinear vibrations of systems with large degrees of freedom and general nonlinearities; 3) new spatial discretization methods for one- and two-dimensional continuous systems; 4) new formulations of flexible multibody dynamics with application to elevator traveling cables; and 5) elastic wave propagation in strongly nonlinear phononic structures.
