Effect of material inhomogeneity on characteristics of a functionally graded hollow cylinder
作者:
Highlights:
• Axisymmetric problem on steady-state oscillations of an inhomogeneous cylinder is formulated.
• The material parameters and density vary along the radial coordinate.
• The direct problem is reduced to a number of canonical ODE systems with variable coefficients.
• The influence of the variable Lame parameters on different field characteristics is analyzed.
• A series of computational experiments are carried out and discussed.
