Teaching Philosophy

My teaching philosophy emphasizes on the belief that knowledge should be accessible to all students. I focus on essential concepts of mechanics, engineering materials, and structures that can prepare students for their selected careers. I prioritize clarity in protocols/steps, rigorous mathematical foundation, inclusive environment, and real-world applications (to make learning more engaging). I also give advice to students so they can maximize their potential to be the next generation of innovators, scientists, engineers, and leaders.

Courses Taught

AERO ENG 4253 – Aircraft Structures II

Level: This course introduces senior-level (4th Year) students to advanced mechanics of structural elements in aircraft/spacecraft structures.

Objective: Students will be able to apply prior knowledge of fundamental mechanics of materials, numerical methods, and aerodynamics to calculate failure onset, stresses via continuum mechanics, stresses via finite element methods, critical buckling load, and vibration response of structural elements of an aircraft. Students will become familiar with basic fatigue, fracture, and aeroelastic parameters utilized for the analysis of aircraft structures.

Topics: Basic aircraft structures and loads, failure theories (Tresca, Rankine, von Mises), bending of thin plates (differential equations, Navier method, energy method), structural instability (buckling of column and plates), matrix methods and finite element analysis (bar, 2D trusses, 3D trusses, beam, triangular, quadrilateral elements, energy methods), mechanics of vibration (single DOF, free vibration, random vibration), fatigue analysis (fatigue life, fatigue crack propagation), fracture mechanics (stress intensity factor, strain energy release rate), and aeroelasticity (divergence, flutter).

Semester taught: Fall 2025

AERO ENG 5238 – Fatigue Analysis

Level: This course is intended for graduate and senior undergraduate students who are interested in the fatigue analysis of load-carrying components/structures subjected to constant amplitude and variable amplitude cyclic loading.

Objective: Students will be able to analyze fatigue life, fatigue crack propagation, fatigue degradation, and fatigue failure of materials (metal, composites, polymers), to understand how fatigue tests are performed and how the experimental dataset can be used for the fatigue investigation.

Topics: Historical perspective of fatigue analysis, fatigue design methods, fatigue testing protocols, fatigue life analysis (S-N diagram: stress-life, strain-life), effect of mean stress (Gerber, Goodman, Soderberg diagram), constant amplitude loading, cumulative damage rules (Miner-Palmgren method), fatigue damage mechanisms at microscale, fracture mechanics approach to fatigue life prediction (effect of notches, fatigue crack propagation, Paris Law, NASGRO model), variable-amplitude loadings, residual stresses, fatigue in bolted and bonded joints, environmental effects on fatigue behaviors (hygro-thermal, corrosive environments), fatigue of additive manufactured materials, introduction to finite-element based fatigue modeling (cohesive zone model), and several guest lectures from academia/industry.
