Pre-requisite Consent of instructor
Co-requisite None
Course Instructor Professor Doyle

No text required; recommended text "Experimental Stress Analysis" by Dally & Riley McGraw-Hill; Course notes "Inverse Problems in Experimental Mechanics," J. F. Doyle

Assessment Method 5 formal lab reports (65%) plus semester experimental project (35%)

Course Objective:

The objective of the course is to solve problems of current technological importance using a range of modern techniques and equipment. The studies are designed to give an understanding of the experimental techniques, an appreciation of the significance of the numbers obtained, as well as to address issues involved in the proper design and reporting of an experiment.

Necessary Background: Mechanics of materials

Topics (number of Lectures):

The lecture material is governed by lab experiments. Following is the list of experiments:

Lab 1: Electrical Resistance Strain Gages

Lab 2: Static Analysis of a Loaded Ring

Lab 3: Thermoelastic Stress Analysis

Lab 4: Beam Vibration

Lab 5: Impact

Lab 6: Longitudinal Wave Propagation

Lab 7: Flexural Wave Propagation

Lab 8: Introductory Photoelasticity

Lab 9: Photoelastic Analysis of a Notched Specimen

Lab 10: Photoelastic Analysis of a Crack

Lab 11: Shadow Moire

Lab 12: Moire Interferometry

Relationship of course to program objectives:

This course emphasizes the experimental solution of problems (2a).
