= EAS4200C: An Introduction =

The University of Florida course EAS4200C Aerospace Structures will emphasize an understanding of mechanics, the ability to properly formulate problems, the ability to judge correctness of a solution and the avoidance of old ad hoc methods of structural analysis. The Finite Element Method (FEM) will be employed in order to solve the Partial Differential Equations that govern aerospace structure mechanics. FEM is also widely used to solve other challenges in engineering and applied math. A specific example is the use of FEM to aid in the exploration of oil reservoirs.

Course Information
Throughout the semester there will be many resources implemented that will encourage learning through lecture notes, assigned readings, cooperative learning assignments as well as in class exams.

Materials
The primary criteria that distinguish aerospace structures are high stiffness, high strength and light weight. The emphasis on light weight is of very high importance to enable aircraft to perform more efficiently in the atmospheric environment where gravity is an issue. Reducing weight allows aircraft to fly higher, faster and with greater endurance. Often, many different materials will be utilized in different areas of the structure depending on the expected loading and functional condition of that element.

Geometry
Of equal consideration to material selection is the geometry of the structure in question. To take full advantage of the material properties, the geometry of each member must be designed to maximize its capability. Typically this means reducing the amount of material in each member to until structural limits are encountered to minimize weight while maintaining an effective margin of safety.
