39 Structural Mechanics

Includes structural element design, analysis and testing; dynamic responses of structures; weight analysis; fatigue and other structural properties; and mechanical and thermal stresses in structures. For applications see 05 Aircraft Design, Testing and Performance; and 18 Spacecraft Design, Testing and Performance.

Definition

Structural Mechanics – The mechanics of structures and the analysis of their behavior under thermal or mechanical loads by means of structural analysis and structural testing.

NASA Interest

Exhaustive Interest : Theory, design, development and testing of structures and structural elements developed for use in aircraft, space vehicles, and launch vehicles; the static and dynamic responses of such structures.

Selective Interest : Theory, design, development, and testing of lightweight or unusual structures or structural elements of potential aerospace use.

Negative Interest : Structures of structural elements of conventional types utilized in bridges, buildings, ships, ocean platforms, heavy transportation, radio and microwave towers, and the like unless specifically aimed at aerospace use.
