elasticity, creep, rotating cylinder, finite difference method

The process of steady-state creep in rotating cylinder with free ends is investigated. Axial symmetry and generalized plane strain in cylinder are assumed. Piecewise linear potential and power creep law are used in problem statement. Finite difference method is utilized to solve governing system of differential equations. Dependences of stresses and strains in cylinder on the time are examined.
