Fully-coupled Computational Modeling of the Dynamic Response of 1-3 Multiferroic Composite Structures. Composite geometry, configuration, and loading parameters were selected following prior experimental studies to simulate realistic operating conditions of the multiferroic structure, where the latter was used to validate the results of the computational model.

Dynamic response of the AHCL sandwich plates. A square simply supported AHCL sandwich plate with thickness h p = 0.1 m under a suddenly applied uniform load q 0 = −10 6 N/m 2 is considered. 8 shows the effect of ratio a/h on the dynamic response of the AHCL sandwich plate under suddenly applied uniform pressure loading. It is observed that the higher the a/h ratio, the higher the amplitude of the plates.

A comparison study between the Craig - Bampton model reduction method and traditional finite element method for. Many studies have shown that the method of dynamic substructuring of Craig-Bampton (CB) which showed the effectiveness, will be used to study the dynamic response of the structure with respect to the excitation frequency [Dennis Klerk et al, 2008.

The amplitude of the deformation- time curve increases when the imperfection coefficient increases. the Winkler and Pasternak foundation on the dynamic response of the plate. From figure 5 we can see that the modulus of the elastic base has a positive effect on the nonlinear dynamic response. On the other hand, it is clearly seen that Pasternak foundation has bigger impact on nonlinear dynamic response than Winkler foundation.

The Poincar´e map distributed in a zigzag curve reflected the chaotic response of the system.. Looking at the basin of attraction and Poinacar´e map, it can be confirmed that the friction force has substantial effects on the dynamic response of the two systems at differ- ent ways. The pure-vibration always has period-1 motion whereas the vibro-impact can be chaotic for several values of the friction force..

In order to verify the ability of the Preisach model to predict transient dynamic response, the dynamic response of the frame subjected to seismic excitation is analyzed. Figure 9 shows the transient dynamic response of the structural lateral displacement in terms of the Ramberg-Osgood model and the Preisach model respectively. The displacement dynamic response history obtained by the Preisach model coincides favourably with that obtained by the Ramberg-Osgood model.

The dynamic response of the beam is computed with the aid of the Newmark method. The obtained numerical result reveals that the variation of the material properties in the thickness and longitudinal directions play an important role on the dynamic response of the beam. A parametric study is carried out to highlight the effect of the material heterogeneity, number of spans on the dynamic response of the beams. The influence of the moving speed is also studied and highlighted..

Structural Models • Free Vibration Analysis 56.5 Forced Vibration Analysis under. (56.1) where D dyn is the maximum dynamic response for deflection, moment, or shear of the structural members and D st is the corresponding maximum static response. The dynamic effects under different speeds of the moving loads and different damping ratios were studied. It was found that the speed of vehicles and the fundamental period of the bridge dominate the dynamic behavior of the bridge.
