Material properties are temperature dependent and graded in the thickness direction with two shell's outer surfaces rich of metal and ceramic in the middle (S-FGM). The shell is subjected to uniform external pressure, axial compressive, electrical loads and resting on elastic foundations. The obtained numerical results are validated by comparing with other results reported in the open literature. date: 2017 date_type: published publisher: Taylor & Francis full_text_status: none publication: Mechanics of Advanced Materials and Structures refereed: TRUE issn: 1537-6494 related_url_url: https://doi.org/10.1080/15376494.2017.1341583 citation: Nguyen, Dinh Khoa and Hoang, Thi Thiem and Nguyen, Dinh Duc (2017) Nonlinear buckling and postbuckling of imperfect piezoelectric S-FGM circular cylindrical shells with metal–ceramic–metal layers in thermal environment using Reddy's third-order shear deformation shell theory.
