The loading parameters calculation of a hollow sphere at the large elastocreep deformations
Abstract:
We presented a model of large elastocreep deformations. Separation of Almansi strain tensor is determined by the quadratic form of reversible and irreversible components. We consider spherically symmetric deformation of a hollow sphere in the steady creep process. Numerical solution of boundary-value problem was obtained. A method for determining loading force on the deformed state was proposed. Functions of the external loading force according to the laws of a given change in the displacement field were constructed.
