Silda Ghazi Mohammed DOORI Doctorate Graduation

The Department of Civil Engineering at Istanbul Gelisim University has achieved a significant milestone by awarding its first doctoral degree. Dr. Silda Ghazi Mohammed DOORI completed her doctoral thesis titled “DYNAMIC ANALYSIS OF AXIALLY SYMMETRIC HETEROGENEOUS PLATES USING THE FINITE ELEMENT METHOD IN THE LAPLACE DOMAIN” under the supervision of Asst. Prof. Ahmad Reshad NOORI. This thesis aims to theoretically investigate the static and forced vibration behavior of axially symmetric plates made of Functionally Graded Materials (FGM).

In the thesis, the material properties were assumed to be isotropic, linear viscoelastic, or elastic, emphasizing the continuous variation of these properties along the thickness of the FG plate. Functionally Graded Porous (FGP) materials were utilized under static loading conditions, while FG materials were employed along the thickness in dynamic scenarios. The novelty of the study lies in the use of quadratic rectangular elements to analyze both the static behavior of FGP plates using the Finite Element Method (FEM) and the damped and undamped forced vibration behavior of FG axially symmetric plates using FEM in the Laplace domain, for the first time.

The findings from this study were compared with existing literature and validated through FEM software results. A high level of agreement was observed between the results of the proposed model and those obtained through different methods.

Moreover, a paper derived from Dr. DOORI's doctoral thesis, titled "Static Response of Functionally Graded Porous Circular Plates via Finite Element Method," was published in the Arabian Journal for Science and Engineering, which is categorized as Q1 in Scopus. This publication further underscores the importance and value of the research at an international level.

We congratulate Dr. DOORI on her graduation from the Civil Engineering Doctoral Program at Istanbul Gelisim University and wish her continued success in her career.
