1993-1994 Catalog Data:Properties of Materials, 2 Credits (1+3P) Physical properties, tests of engineering materials. Corequisite: CE 301.

Textbook:The Testing of Engineering Materials by Harmer E. Davis, et al. 4th Edition, McGraw Hill.

Reference:ASTM Standards

Coordinator:John Minor, PE, Professor of CE

Goals:To gain familiarization of standard testing procedures. To introduce basic techniques of research. To study test formulation and foster critical appraisal of laboratory techniques. To study data evaluation and develop informal and formal reporting procedures

Prerequisite by topic:

• 1.English-reading & writing
• 2. Math including Algebra and Statistics
• 3. Statics/Mechanics of Materials

Topics:

• 1. Testing--Data, Standards, Methods (2 Classes)
• 2. Metal--Properties, Specifications, Tests (3 Classes)
• 3. Concrete--Design, Mixing, Tests, Properties (3 Classes)
• 4. Other Materials-- Timber, Plastics (2 Classes)
• 5. Mechanics (3 Classes) 6. Exam (1 Class)

Computer Usage: Students are encouraged to use word processors and spread sheets in the preparation of reports.

Laboratory Projects: CE 311 is basically a laboratory course, consequently, the student gets hands-on experience in formulating, running, and interpreting standard and non standard tests. Results are reported in formal, non- formal, letter, and memo formats. The form of the reports vary with the instructor and the particular conditions.

• 1. Machine and instrumentation familiarization and verification. The student learns to run typical testing machines and deformation measuring devices. These projects are reported in letter and non-formal reports. (2 weeks)
• 2. Metal testing. The student observes through standard ASTM tests and non standard methods the critical properties of steel, aluminum, and other metals. Tests include tension tests, hardness tests, impact tests, fatigue tests, torsion tests, and creep tests. Specifications are consulted and discussed. Results are reported in formal, letter, and memo type reports. (4 weeks)
• 3. Concrete. The student designs a typical mix, makes the mix and tests the resulting concrete. Designs include an economical mix and a home mix. Tests include, material including graduation and bulk density, slump, appearance, proper specimen preparation, capping, compressive cylinder tests at 7 day and 28 day including stress strain, air content, etc. This information is compiled and normally reported in a formal report. (3 weeks)
• 4. Timber. Tests are run to determine some of the properties of timber. These include compression parallel to the grain, compression perpendicular to the grain, direct shear, and static bending. Normally the results are reported in a letter or memo type report. (1 week)
• 5. Mechanics. Tests are conducted relating the theory of mechanics of materials to the actual situation. These tests include elastic curve, principal strain, elastic and column tests. These are normally reported in an informal way. The student project normally overlaps these periods. (2 weeks)
• 6. Student Project. The student is required, as groups, to define a problem, design a simple test, conduct the test, and report the results. Topics vary with the imagination of the student and in the past have included fishing line strength as compared to "pound test," bicycle spokes, compressive strength of various beer cans, et al. The type of report is flexible. (2+ weeks)
