Mathematical simulation of the effects of creep anisotropy on stressed-deformed state of channel tubes

Creators

Description

Methods of calculating anisotropic channel tube deformation are presented. An example of calculating stressed-deformed state of the RBMK channel tubes is given. A strong effect of creep anisotropy and coolant pressure drop on the tube deformation is demonstrated. Algorithm for calculational determination of optimal creep anisotropy coefficients, under which axial and radial displacements of channel tubes do not exceed the assigned limiting values, is proposed
