AAE55200 - Nondestructive Evaluation of Structures and Materials

Spring 2015

Days/Time: MWF / TBA
Credit Hours: 3

Learning Objective:
Overview the concepts, principles, and methods employed for nondestructive evaluation (NDE) of structures and materials. While emphasis is on inspection methods employed to ensure structural integrity of aerospace vehicles, course content has general application to a broad class of high performance structures. Major NDE techniques covered include X-rays, ultrasonics, eddy currents, penetrants, magnetic flux, visual/optical, acoustic emission, and thermal imaging methods. Further topics such as damage-tolerant design, retirement-for-cause, factors affecting NDE reliability, and structural "aging" will be discussed in the context of NDE engineering.

Description:
This course overviews the concepts, principles, and methods employed for nondestructive evaluation (NDE) of structures and materials. All major NDE techniques are covered, including X-rays, ultrasonics, eddy currents, penetrants, magnetic flux, and visual/optical methods. Other new emerging inspection methods are also discussed. While emphasis is on inspection methods employed to ensure structural integrity of aerospace vehicles, course content has application to a broad class of high performance structures. The presentation attempts to strike a balance between the physical principles of each NDE method and the method's application to inspection problems. Further topics such as damage-tolerant design, retirement-for-cause, factors affecting NDE reliability, and structural "aging" are discussed in the context of NDE engineering. Tentative Syllabus (PDF)

Topics Covered:
Introduction to nondestructive evaluation (the role of NDE in maintaining structural integrity, requirements for an effective NDE technique, inspection reliability); Visual inspection methods; Penetrant methods; Radiographic techniques; Ultrasonic inspection; Eddy current techniques; Magnetic techniques; Other inspection techniques (acoustic emission, proof testing, thermal imaging, new emerging techniques, etc.); Applications of NDE to manufacturing, aging structures, and composite materials.

Prerequisites:
A second level course in aeromechanics or a mechanics of materials course; or equivalent undergraduate course in strength of materials.

Applied/Theory: 50/50

Web Content:
Syllabus, grades, lecture notes, homework assignments, solutions, chat room, and message board.

Homework:
Although homework assignments may be made, they will not be collected or graded.

Projects:
Required, not job-related. Two term papers account for 45% of the course grade. Paper 1 (20%)-- a written literature review that describes a new research topic in NDE. Paper 2 (25%) -- a written paper and powerpoint presentation dealing with application of NDE methods to a practical engineering situation. The powerpoint presentation will be posted on the course website for review by the rest of the class.

Exams:
One midterm exam (25% of course grade) and a comprehensive final exam (30% of course grade).

Textbooks:
Required--A. F. Grandt, Jr., "Fundamentals of Structural Integrity: Damage Tolerant Design and Nondestructive Evaluation," John Wiley and Sons, 2004, ISBN 0-471-21459-0.

Computer Requirements:
ProEd minimum computer requirements; course assignments and handouts will be posted to course web.
