PhD degree in mechanical engineering at (UD) U. of Dayton, GPA 3.33/4, 2014. Courses: Principal of Materials I, Internal Combustion Engines, Principal Materials Selection, Theory of Elasticity, Introduction Polymer science, Analyses Mechanical -Composite, Finite Element Analyses.

PhD Dissertation:

Analytical mechanics of hybrid and non-hybrid composite material by simulation and experimental analysis. The research focused on hybrid materials consisting of both glass and carbon fiber embedded in a polymer matrix, undergoing mode I, mode II, and mix mode I/II static inter-laminar fracture. Glass fiber panels, carbon fiber panels, and hybrid panels were fabricated using the wet layup / vacuum bag technique. The non-hybrid all-glass, all-carbon, and hybrid glass/carbon were experimentally characterized by quasi-static testing in load frames. The specimen and material geometries (especially at material interfaces) were analyzed using the finite element method in Abaqus. From experiments, the resulting fracture surfaces were investigated using a scanning electron microscope and were co-related with the FE results. Under Work Journal Paper:
