The article titled “Dynamic analysis of elastic and viscoelastic FGM rectangular plates,” authored by Asst. Prof. Ahmad Reshad NOORI, Chair of the Civil Engineering Department, has been published in a Q2-ranked journal within Sage Journals.
The study investigates the free and forced vibration behavior of functionally graded material (FGM) rectangular plates using finite element analysis implemented in ANSYS. The material is assumed to be linear elastic with properties varying continuously through the thickness. Shear deformation effects are incorporated via the first-order shear deformation theory, while the viscoelastic behavior of the plates is modeled using the Kelvin damping approach.
For forced vibration analyses, step and impulsive loads are considered, and the optimum number of layers required for discretizing FGM plates is determined to accurately capture natural frequencies and transient responses. The effects of material gradient index, boundary conditions, damping ratio, and loading type on the dynamic behavior are comprehensively examined. The results indicate that increasing the material gradient index leads to higher response periods and amplitudes, whereas boundary conditions have a comparatively smaller influence.
The department congratulates Asst. Prof. Ahmad Reshad NOORI on this valuable scientific contribution and wishes him continued success in his academic research.
