The Real World of Engineering -
The Transition from Classroom to Workplace
Mr. Wendell Maciejewski
Mr. Wendell Maciejewski has 40+ years as a Mechanical Engineer, mixing in 10 years in various manufacturing companies, working on such products as mailing machines and copiers, mechanical counters and gasoline computers, consumer sewing products and glass manufacturing combined with 32 years in Navy submarine research, where he worked with submarine hull arrays, environmental testing, materials testing and more recently in the Electromagnetics Department, where he supports Navy Imaging, Electronic Warfare and Submarine Communications programs. He holds an Associate degree in Mechanical Engineering Technology from Thames Valley State Technical College, a Bachelor’s degree in Mechanical Engineering and a Master’s degree in Metallurgy from the University of Connecticut. He has 15 patents and numerous Navy Technical Documents. He is currently a supervisor of a mechanical engineering branch, which he has held for 12 years.
Description: (Lecture, 3 credits) Introduction to the basic concepts of the mechanical behavior of composite materials. Analysis and performance of fiber-reinforced composites. Special design considerations and experimental characterization of composites.
Pre-requisite: CVE 220 or permission of instructor.
Learning Objectives: After completing this course, the student will be able to:
- predict composite properties based on micromechanical theories
- perform stress and strain analysis in anisotropic and orthotropic materials having continuous fiber reinforcement
- model thermal/moisture effects on mechanical properties of CFRC composite materials.
- use Classical Lamination Theory to examine the role of individual plies on the global and local axial, bending and twisting deformation of laminates.
- use failure theories for multiaxial loading to determine the composite survivability.

Class Time and Place: TTh 11:00 am – 12:15 pm, Wales Hall 225
Office Hours: M 10:00 am – 12:00 pm, W 1:00 pm – 3:45 pm
Text: No required book
Reference Material: Handouts and lecture notes, suggested texts on composites:
- Stress Analysis of Fiber-Reinforced Composite Materials, Michael Hyer, McGraw Hill, 1997
- Mechanics of Composite Materials with MATLAB, George Voyiadjis and Peter Kattan, Springer-Verlag, 2005
- Homework 10%
- Composite Program
- Quizzes 20%
- Exams 70%
- Attendance requires signing of attendance sheet during class.
- Participation includes class discussions or problem solving.
- No late homework will be accepted.
- Collaboration in the form of discussion of formulation of solutions or results is encouraged; however, each individual must work independently to create the solution, computer programs, and the homework report.
Course Requirements: Only the basic concepts introduced in an undergraduate strength-of-materials course is necessary. The course, however, requires the knowledge of matrix analysis as well as the use of computational programs (examples are: MATLAB, Mathematica, Maple, or macros in Microsoft Excel).
