Professor Emeritus of Mechanical Engineering

Introduction

My areas of interest include solid mechanics, dynamics, mechanical vibrations, and the finite element method. I taught undergraduate and graduate-level courses in these subjects at CSULA as a professor from 1979 to 2010. From 2016 to 2018, I taught ME 4230, Finite Element Analysis as a part-time lecturer. The ME Department offers programs towards Bachelor of Science degrees and Master of Science degrees in Mechanical Engineering.

I hold memberships in the following professional and two honor societies:

ASME (The American Society of Mechanical Engineers),
Pi Tau Sigma (The Mechanical Engineering Honor Society),
Tau Beta Pi (The National Engineering Honor Society). I was initiated by the California Epsilon Chapter.

I was a member of the CSULA teams that designed, analyzed, built, tested, and raced three solar-cell powered cars:

the Solar Eagle car, in GM Sunrayce USA (1990) from Florida to Michigan,
the Solar Eagle II car, in Sunrayce 93 from Texas to Minnesota,
the Solar Eagle III car, in Sunrayce 97 (June 19-28, '97) from Indiana to Colorado. The Flight of the Solar Eagle III.

The first Solar Eagle car was on display at the Petersen Automotive Museum until 1997. The Solar Eagle II car is on display at the California Science Center.

The Solar Eagle III car finished in first place in Sunrayce 97!

The Solar Eagle III car driven by Roman Vasquez crosses the finish line in Colorado Springs followed by our "chase" vehicle in which I am riding with the "strategy" group of our team.

The Solar Eagle III car was among the 1998 First Editions of Hot Wheels by Mattel.

I worked on the structural analysis of the Solar Eagle III car. I have also been involved in weathe r and insolation forecasting for all three Solar Eagle projects.

I was born in Budapest, Hungary. I was raised and attended school in Munich, Germany, Buenos Aires, Argentina, Toronto, Canada, and Los Angeles. As my family moved from one country and language to the next, my first name changed, through translation, from "István," to "Stefan," to "Esteban," to the present "Stephen," or "Steve" for short. My last name is pronounced "fel-se-gie." When it is pronounced in Hungarian, the stress is on the first syllable, but, in English, I put the stress on the second syllable. Hungary celebrated in 1996 its millecentenary (896-1996).

Teaching Interests

My primary goal is to teach the subjects in my areas of interest from the viewpoint of what knowledge a potential engineering employer might expect from a new engineering graduate. Before I began teaching full time, I worked as a mechanical engineer for the Garrett Corporation (now Honeywell/Aerospace), where I analyzed and designed heat exchangers for aerospace applications, and the Hughes Aircraft Company (now merged with Raytheon), where I analyzed and designed tactical missile structures.

I began my teaching career as a part-time lecturer at the Univ. of Southern California where I taught for several years an undergraduate level dynamics course. Following this, and before coming to CSULA in 1979, I was a full-time lecturer at U. C. Santa Barbara where I taught for one year various undergraduate and graduate level courses in mechanics and engineering mathematics.
