Title:
On application of a linear fractional creep and creep rupture strength model in simulation of long-term destruction of typical structural elements in an active medium
The long-term destruction of the shell and plate during creep in the active medium under the conditions of an unsteady complex stress state is investigated. The influence of the medium on the time to fracture is taken into account by introducing a function of the integral average concentration of the medium into the constitutive and kinetic linear-fractional relationships. Comparison of the times to failure using the scalar and vector damage parameters is carried out. The features of using a linear-fractional model to describe long-term fracture processes are determined.
