Education

Sharif University of Technology__________________________________________Tehran, Iran

M.Sc. in Mechanical Engineering (September 2007 – Present)

Overall GPA: 16.76 / 20

Thesis: "Vibration analysis of a cracked Timoshenko beam with a continuous model for crack".

In this thesis, I began with studying of Timoshenko beams for crack in the horizontal and vertical faces. The model of crack used in this thesis is the most recently developed model for crack in the beam and rotor, developed by my M.Sc. supervisor. Then, I extended this model to Timoshenko (short) rotors by export the beam model to rotating coordinates. As results of this research, I studied the effect of crack properties- depth and location- and unbalance force on the dynamic behavior of rotors- such as orbit diagram, frequency response function (FRF)-.

Islamic Azad University of Mashhad____________________________________Mashhad, Iran

B.Sc. in Mechanical Engineering _(September 2003 - June 2007)

Total GPA: 17.8 / 20

Thesis: "Studying the properties of all six-stroke engine types."

It is essential to improve the efficiency of conventional engines to overcome the environmental and fuel crises. Therefore, in this thesis I studied six-stroke engines as a potential engine with a high efficiency for future cars. At this time, the six-stroke engines are all in concept but they have possibility to become the future engine for our cars.
