Journal ArticleDOI
Analysis and modeling the size effect on vibration of functionally graded nanobeams based on nonlocal Timoshenko beam theory
Omid Rahmani,O. Pedram +1 more
TL;DR: In this article, the effects of the gradient index, length scale parameter and length-to-thickness ratio on the vibration of functionally graded material (FGM) nanobeams were examined.
Journal ArticleDOI
Free vibration response of composite sandwich cylindrical shell with flexible core
TL;DR: In this article, the free vibration analysis of composite sandwich cylindrical shell with a flexible core using a higher order sandwich panel theory is presented. But the analysis is restricted to the case of composite shells.
Journal ArticleDOI
Finite element modeling of low-velocity impact on laminated composite plates and cylindrical shells
TL;DR: In this paper, composite laminates and shell structures subjected to low-velocity impact are investigated by numerical analysis using ABAQUS finite element code, by considering several case studies with various conditions, validity of the existed modeling processes is examined.
Journal ArticleDOI
Buckling analysis of functionally graded nanobeams based on a nonlocal third-order shear deformation theory
Omid Rahmani,A. A. Jandaghian +1 more
TL;DR: In this paper, a general third-order beam theory that accounts for nanostructure-dependent size effects and two-constituent material variation through the nanobeam thickness, i.e., functionally graded material (FGM) beam is presented.
Journal ArticleDOI
Free vibration analysis of sandwich structures with a flexible functionally graded syntactic core
Omid Rahmani,Seyyed Mohammad Reza Khalili,Seyyed Mohammad Reza Khalili,K. Malekzadeh,Homayoun Hadavinia +4 more
TL;DR: In this paper, a high-order sandwich panel theory is implemented to free vibration analysis of sandwich beams with syntactic foam as a functionally graded flexible core, which can achieve to high order effect caused by the nonlinearity of the longitudinal and vertical deformations of the soft FG core.
