Elasticity in Aerospace Engineering


Credit Hours:


Learning Objective:

To give the student an in-depth background in mechanics of solids including large deformation, and the ability to perform stress analyses in elastic bodies, especially two-dimensional bodies.


A basic course in the theory of elasticity, with emphasis on understanding the fundamental principles and solution techniques used in the stress analysis of elastic solids and structures. Cartesian tensors are introduced for formulations of general deformations and states of stress. Constitutive relations and field equations are derived for large deformation and then reduced to small deformation. Two dimensional problems are solved by using the Airy's stress function method and complex functions approaches. Energy methods and approximate solutions using variational principles are included.
