Solid Mechanics

The concepts of stress and strain and their tensor properties. Elastic stress strain relations. Analysis of stress and deformation in members subject to axial, torsional, bending and combined loading. Column stability.

This is a fundamental course in engineering used to develop the ability to logically and methodically analyze problems in solid mechanics. Emphasis is placed on understanding the principles employed in problem solutions rather than reliance on substitution and memorization.

1. Develop an understanding of stress, axial loading, torsion, beam bending, pressure in thinwalled cylinders and spheres, stress and strain transformations, and failure theories.2. Employ Large Deflection Beam Theory to address cantilever beam problems associated with axial loading and transverse loading.3. Understand elasticity equations for torsion problems, including non-circular cross sections, elliptical cross sections, and shafts of variable diameter.4. Develop an understanding of plane stress, plane strain, and both the 2-D and 3-D equations of elasticity.5. Analyze 2-D problems in rectangular coordinates (polynomial solutions) for a cantilever beam with an end load or a simply supported beam with a uniform load.6. Solve for deflection of beams with the Double Integration Method as well as the Moment-Area Method.7. Solve 2-D problems in polar coordinates that deal with the elasticity equations, thickwalled pressure vessels, plates with a hole, stress concentrations, point loads on a halfspace, point loads on a wedge (non-prismatic beams), and bending of a curved beam.8. Analyze failures in different classes of columns.

Located on the Daytona Beach Campus, the Jack R. Hunt Library is the primary library for all students of the Worldwide Campus. The Chief Academic Officer strongly recommends that every faculty member, where appropriate, require all students in his or her classes to access the Hunt Library or a comparable college-level local library for research. The results of this research can be used for class projects such as research papers, group discussion, or individual presentations. Students should feel comfortable with using the resources of the library.

Students are also required to have a calculator. Graphing calculators are not required (they are quite complicated and expensive), but a basic scientific calculator is necessary (with buttons representing the trigonometric functions of SIN, COS, and TAN; they are typically found starting around $10). Whatever calculator you decide to use, be sure that you know how to use it, as this will alleviate a lot of mistakes and frustration.
