Course Objective

The aim of this course is to introduce the student to the analysis of linear elastic solids under mechanical and thermal loads. The primary intention is to provide for students the essential fundamental knowledge of the theory of elasticity together with a compilation of solutions of special problems that are important in engineering practice and design. The topics presented in this course will also provide the foundation for pursuing other solid mechanics courses such as theory of plates and shells, elastic stability, composite structures and fracture mechanics.

Learning Outcomes of the Course Unit

1   Ability to define an elasticity problem
2   Ability to determine/explain the main concepts in elasticity such as plane stress, plain strain, equations of equilibrium, boundary conditions, compatibility equations and stress function
3   Ability to compare advantages and disadvantages of different solution strategies
4   Ability to select the best solution method to solve an elasticity problem
5   Ability to discuss the results of a solution and compare them with those of elementary level
