inhomogeneity, pipe, anisotropy, deformed state.

The deformed state of an anisotropic nonlinear inhomogeneous pipe is considered. Let us take the material inhomogeneity as the dependence of the yield stress on coordinates. For material heterogeneity are capable of influencing factors such as: shock effects, temperature, radiation exposure and others. Along the elliptical curves, the yield stress is assumed to be constant. Results taking into account the effect of anisotropy on stress-strain state of various structures and physicality in demand in the modern world.
