Description
This course introduces the basic concepts and methods of elasticity theory, which is the study of how materials deform and stress under external forces. The course objectives are to enable the students to:Understand the definitions and notations of forces, stresses, strains, and Hooke's law in two and three dimensions.Apply the transformation of stress and strain components under different coordinate systems.Identify the principal stresses and strains, stress and strain invariants, strain energy, and superposition principle.Solve two-dimensional problems in Cartesian and polar coordinates using Airy's stress function method.Analyze torsion of bars with different cross-sectional shapes using stress function, energy, and numerical methods.The course will also expose the students to some experimental techniques and analytical tools for solving elasticity problems, such as soap films and Prandtl's membrane analogy. The course will require the students to apply the concepts and methods learned in class to solve homework assignments and design projects. The course will also prepare the students for more advanced courses in solid mechanics, such as plasticity, fracture mechanics, and finite element analysis. The course is suitable for students who have completed courses in engineering mechanics, mathematics, and physics.
