Web2. A linear-elastic–nonlinear-swelling model for displacement. The model derived in Part 1 can be summarised briefly as follows. When placed in water and allowed to swell without any external constraints, a hydrogel will reach a temperature-dependent fully swollen state in which the polymer volume fraction $\phi = \phi _0$ is uniform. In the case of super … Webfraction is to be determined. This is particularly important for hybrids because the size scale over which variations occur is usually much larger than it is with composites having only a …

WebHence, the model allows the estimation of resonance frequencies of 1-3 composite transducers. This model has been extended to cover more material parameters, and they are compared to experimental results up to PZT volume fraction nu of 0.8. The model covers calculation of piezoelectric charge constants d(33) and d(31).
