Steady State Model

Here we investigate the kinetic model for the large deformation theory of hydrogel under the outside stimulations. We present the large deformation dynamical model in the following two points. (1) The phase transition caused by the deformation gradient is concerned, which makes the model more integral. (2) Based on the steady-state model, the time-dependent large deformation model is proposed and the time developing process is investigated. Considering the force of the large deformation, we introduce the heat equation to express the transformation of the chemical potential. The extended model can be used to describe the development of the large deformation. We present numerical examples of the cylindrical hydrogel for one- and two-dimensional cases under pressure and stretch. Besides, some key parameters are studied to test the model.

Calculation Procedures

An approximate analytical large deformation method, based on the Nadai deformation theory, for calculating the burst speed of aeroengine disks, is presented in this paper. The basic equations are developed and the calculation procedures are illustrated. The burst speeds are calculated for some tested disks, and the calculation results are compared with the test results; the differences between two results are shown to be less than 8 percent. This shows that the new method is both simple and convenient. Therefore, it could be employed in the development of aeroengine disks.
