Static behavior of FGM cylindrical panel with porosities in hygro-thermal environment

Tạp chí Khoa học và Công nghệ
In this study, the deflection and stress field of perfect and imperfect (with and without porosities) functionally graded (FG) cylindrical panels are determined following the first-order shear deformation theory (FSDT).
