Introduction Many porous materials, such as filter materials made of sintering metals, lagging materials, fireproof materials and so on, are utilized for various fields.
The authors[5],[6] also have dealt with statical problems and dynamical ones of axisymmetrical shells made of porous materials.
Then in this paper the dynamic problems of non-homogeneous (the functionally graded) porous shells of revolution made of such materials are treated.
